It contains numbers, upper and lowercase English letters, and some special characters. Since many web sites declare ISO and use the values from to as if they were using Windows, most browsers will display these characters from the Windows character set instead of nothing. The higher part of ISO codes fromexcept and contains characters used in Western European countries.

It is also commonly used in most standard romanizations of East-Asian languages. It is the basis for most popular 8-bit character sets and the first block of characters in Unicode. This and similar sets are often assumed to be the encoding of 8-bit text on Unix and Microsoft Windows if there is no byte order mark BOM ; this is only gradually being changed to UTF Code page a. Windows is used for it in Windows. Each character is encoded as a single eight-bit code value.

These code values can be used in almost any data interchange system to communicate in the following languages:.

ISO was commonly used [ citation needed ] for certain languages, even though it lacks characters used by these languages. In most cases, only a few letters are missing or they are rarely used, and they can be replaced with characters that are in ISO using some form of typographic approximation.

The following table lists such languages. Also, this scheme does not provide for oriented 6- or 9-shaped single or double quotation marks. Some fonts will display the spacing grave accent 0x60 and the apostrophe 0x27 as a matching pair of oriented single quotation marks, but this is not considered part of the modern standard.

BraSCII matches the original draft. Inthe very first version of Unicode used the code points of ISO as the first Unicode code points. This map assigns the C0 and C1 control codes to the unassigned code values thus provides for characters via every possible 8-bit value. Since their original code points were now reused for other purposes, the characters had to be reintroduced under different, less logical code points. It is very common to mislabel Windows text as being in ISO A common result was that all the quotes and apostrophes produced by "smart quotes" in word-processing software were replaced with question marks or boxes on non-Windows operating systems, making text difficult to read.

Many web browsers and e-mail clients will interpret ISO control codes as Windows characters, and that behavior was later standardized in HTML5. The Apple Macintosh computer introduced a character encoding called Mac Roman in It was meant to be suitable for Western European desktop publishing. It is a superset of ASCIIand has most of the characters that are in ISO and all the extra characters from Windows but in a totally different arrangement.

The few printable characters that are in ISObut not in this set, are often a source of trouble when editing text on Web sites using older Macintosh browsers, including the last version of Internet Explorer for Mac.

With the latest release flask 1. I was waiting for this change and it seems to work great using the builtin dev server. However, gunicorn on the production server does not support latin-1 encoding for the headers and only supports ascii. Originaly flask also opted for ASCII encoding, however commit d6a4 changed this and since then latin-1 is used.

What was the rational to switch to latin-1? Werkzeug encodes with Latin-1 in many other places, including the encoding dance, so I'm not sure why it didn't cause issues before. Can I get an example of a filename that caused Gunicorn to raise an error? Lines to in da. Here's the code for the filename header I replaced 'latin-1' with 'ascii' locally :. The filename is encodable as Latin-1, so it's passed through as-is.

Now, I'm not too keen on character encodings Is there a spec for this or maybe a list of allowed characters for an HTTP-header "value"? Some non-ASCII bytes are allowed for backwards compatibility, but are not supposed to be displayable. Please read comments first, this answer likely draws wrong conclusions from the right sources, needs edit. Edit : may not be obvious at first, the character encoding defined in the header only applies for the response body, not for the header itself.

I'd like to sum up all the relevant definitions as per the spec linked by Penchant. TEXT is the most general and includes all the rest -so forget about the rest. Learn more. Ask Question.

Pacerier Kornel Kornel To expand a bit on a very useful answer: "UTF-8" is the character set, and "Q" means the value will be "quoted-printable".

What exactly should the HTTP recipient do when it receives these "opaque data"?

ISO/IEC 8859-1

Pacerier "opaque data" means it's a black box with a bunch of bytes that applications shouldn't try to display or interpret like binary data. What happens with it depends on the header, might range from "nothing" to "discard".When a server sends a document to a user agent eg. This information is expressed using a MIME type label.

This article provides a starting point for those needing to set the encoding information in the HTTP header. You should look elsewhere for information about how to declare character encoding in HTML pagesor how to find out how to check the character encoding information being sent in an HTTP header.

It is very important to always label Web documents explicitly. HTTP 1. But there are too many unlabeled documents in other encodings, so browsers use the reader's preferred encoding when there is no explicit charset parameter.

In theory, any character encoding that has been registered with IANA can be used, but there is no browser that understands all of them. The more widely a character encoding is used, the better the chance that a browser will understand it. A Unicode encoding such as UTF-8 is a good choice for a number of reasons. How to make the server send out appropriate charset information depends on the server. You will need the appropriate administrative rights to be able to change server settings.

This can be done via the AddCharset Apache 1. With AddDefaultCharset Apache 1. For more information, see the article on Setting 'charset' information in. Use an indexer in JigAdmin to associate extensions with charsets, or set the charset directly on a resource.

IIS 5 and 6. Put in the extension you want to map, separately for each extension; IIS users will probably want to map.

Output the correct header before any part of the actual page. After the last header, use a double linebreak, e. Use the same solution as for Perl except that you don't need a semicolon at the end. Use the header function before generating any content, e. Java Servlets. Use the page directive e. Also, the page itself is interpreted as being in this encoding.

ContentType and charset are set independently, and are methods on the response object. To set the charset, use e. Net, setting Response.

ContentEncoding will take care both of the charset parameter in the HTTP Content-Type as well as of the actual encoding of the document sent out which of course have to be the same. The default can be set in the globalization element in Web. Setting charset information in.Unicode is a standard encoding system for computers to display text and symbols from all writing systems around the world.

On the Unicode website you can read the following definition for Unicode: Unicode provides a unique number for every character, no matter what the platform, no matter what the program, no matter what the language. View the conversion routines. You can use. Apache's default character set is ISO Apache will use this character set in the HTTP header it sends back to the browser after a request. To serve just your. You can also create a new extension index. You must use this function before any output is sent to the browser.

Both versions will work in HTML5. The long version will overrule the short one and HTTP headers will overrule both. Browsers might ignore this statement if your document has a BOM-header see below. BOM-headers might give problems with some scripting languages such as PHP you will see some strange characters -the BOM header- flashing for a fraction of a second before a page is loaded.

Used on the body itself, Content-Disposition has no effect. Only the value form-dataas well as the optional directive name and filenamecan be used in the HTTP context. The first parameter in the HTTP context is either inline default value, indicating it can be displayed inside the Web page, or as the Web page or attachment indicating it should be downloaded; most browsers presenting a 'Save as' dialog, prefilled with the value of the filename parameters if present.

The first parameter in the HTTP context is always form-data. Multiple parameters are separated by a semi-colon ';'. This simple HTML file will be saved as a regular download rather than displayed in the browser. Most browsers will propose to save it under the cool.
