The Cyrillic character щ now has a code point value of 1097.īytes these days are usually made up of 8 bits. While the letter é is still represented by the code point value 233, In fact, UnicodeĬontains, in a single set, probably all the characters you are likely to ever need. For example, with the Unicode character set, you can represent both characters in the same set. There are other ways of handling characters from a range of scripts. Note that it is only the context that determines whether that byte represents either é or щ. These character sets contain fewer than 256 characters and map code points to byte values directly, so a code point with the value 233 is represented by a single byte with a value of 233.
However, in ISO 8859-5, the same code point represents the Cyrillic character щ. In the coded character set called ISO 8859-1 (also known as Latin1) the decimal code point value for the letter é is 233. Unicode code point values are typically written in the form U+00E9. For example, 233 in hexadecimal form is E9. Note that code point numbers are commonly expressed in hexadecimal notation - ie.

Feel free to just skip to the section Further reading. This section provides a little additional information on mapping between bytes, code points and characters for those who are interested.
The links below provide some further reading on these topics. (Ideally, you would use UTF-8 throughout, and be spared this trouble.) (It's usually the default these days.) You may also need to check that your server is serving documents with the right HTTPĭevelopers need to ensure that the various parts of the system can communicate with each other, understand which character encodingsĪre being used, and support all the necessary encodings and characters.

Throughout your system also removes the need to track and convert between various character encodings.Ĭontent authors need to find out how to declare the characterĮncoding used for the document format they are working with.ĭeclaring a different encoding in your page won't change the bytes you need to save the text in that encoding too.Īs a content author, you need to check what encoding your editor or scripts are saving text in, and how to save text in UTF-8. This Unicode encoding is a good choice because you can use a single character encoding to handle any character you are likely to need. For example:Īs a content author or developer, you should nowadays always choose the UTF-8Ĭharacter encoding for your content or data. See a square box, a question mark or some other character instead.

If your font doesn't have a glyph for a particular character, some browsers or software applications will look for the missing glyphs in otherįonts on your system (which will mean that the glyph will look different from the surrounding text, like a ransom note). (Of course, if the encoding information was wrong, it will be looking up glyphs for the wrong characters.)Ī given font will usually cover a single character set, or in the case of a large character set like Unicode, just a subset of all theĬharacters in the set. Once your browser or app has worked out what characters it is dealing with, it will then look in the font for glyphs it can use to display definitions of the shapes used to display characters. How do fonts fit into this?Ī font is a collection of glyph definitions, ie. You will just need to be sure that you consider the advice in the
Most of the time, however, you will not need to know the details. The section Additional information provides a little more detail for those who are interested. many different ways of mapping between bytes,Ĭode points and characters. Unfortunately, there are many different character sets and character encodings, ie. So, when you input text using a keyboard or in some other way, the character encoding maps characters you choose to specific bytes in computer memory, and then to display the text it reads the bytes back into characters. You shouldīe aware of this usage, but stick to using the term character encodings whenever you can. The misleading term charset is often used to refer to what are in reality character encodings. Without the key, the data looks like garbage. It is a set of mappings between the bytes in the computer and the characters in the character set. A character encoding provides a key to unlock (ie. Basically, you can visualise this by assuming that all characters are stored in computers using a special code, like the ciphers used in espionage.
