Thus the fact that 4. Note that the statistics for 1. To help understand what we're talking about, here are some definitions of some of the terms used in the table see Section 2.
The Unicode Standard is intended to support the needs of all types of users, whether in business or academia, using mainstream or minority scripts. A: The short answer is that as of Version The long answer is rather more complicated, because of all the different kinds of characters that people might be interested in counting. To dive into this question in detail, see Unicode Statistics.
A: It's hard to say, because Unicode encodes scripts for languages, rather than languages per se. Many scripts especially the Latin script are used to write a large number of languages. Unicode also includes many historic scripts used to write long-dead languages, as well as lesser-used regional scripts that may be used as a second or even third way to write a particular language.
See Supported Scripts for the full list. See also the list of Languages and Scripts. A: The Unicode Standard encodes characters on a per script basis. So, for example, there is only one set of Latin characters defined, despite the fact that the Latin script is used for the alphabets of thousands of different languages.
The same principle applies for any other script Cyrillic, Arabic, Ethiopic, Devanagari, However, the Unicode Standard does not encode scripts per se.
For a listing of scripts and their names, see Supported Scripts. A: Both and Unicode specify the same character encoding: they contain the same characters at the same locations. They remain fully synchronized even as they are extended to cover additional characters. Q: I think my company might want to get involved in Unicode. Is there any material that I can use to present the case to my management? A: Yes, there is a white paper outlining the overall value proposition of a Unicode membership to an organization.
See Why Join and How to Join. A: The Unicode Standard is not a software program, nor is it a font. It is a character encoding system, like ASCII, designed to help developers who want to create software applications that work in any language in the world. If all you need is to create a multilingual text or write a document or send e-mail in another language, then a Unicode-compliant text editor, mail program, or word processing package will do the job.
Please see the following pages on our web site for further information about the standard and where to look for help:. Basic information about " What is Unicode? In addition to the pages listed above, please see:. Frequently Asked Questions Unicode mail list online discussion forum Q: My computer cannot display some of the latest Unicode symbols I need.
I tried downloading and extracting the latest Unicode data files from the Unicode web site, but it has no effect on the characters my computer can display or type.
How can I display and type the latest Unicode characters? A: The Unicode data files do not function like a software patch, and cannot automatically update existing fonts or applications, so downloading the files will not help in displaying and typing the Unicode characters needed.
The reason you don't see the characters as expected is most likely because you need to install a font that covers the set of Unicode characters you are trying to see. Other possible reasons might be that:. If you need to install a font to resolve the problem, free fonts can be downloaded for many Unicode ranges. See Font Resources , or search in your browser for the name of the font you need.
Fonts typically cover only one script, or sometimes a range of scripts. Often fonts haven't been updated to render the most recent additions to the Unicode character set. If a code point is too small to take up 6 hexadecimal digits, add zeros in front of the number until it is 6 digits long.
The first two hexadecimal digits are 10 which translates to 16 in decimal digits. Tutorials About RSS. Unicode Code Points As mentioned earlier, each unicode character is represented by a unicode code point which is an integer value. Special Characters Unicode contains some special characters which do not represent textual characters. Unicode Planes Unicode code points are divided into sections which are called unicode planes. Non-character Code Points The last 2 characters of each unicode plane are non-characters.

Simon Nickerson Simon Nickerson According to these "planes" even the last three byte of a 4 byte char could express 64 of them. Am I wrong? Yes, that is for synchronization, see cl. That's outdated I think. Andy: That makes sense: the original spec for UTF-8 worked for bigger numbers. The bit limit was a sop to the folks who had locked themselves into bit characters, and thus did UCS-2 beget the abomination known as UTF Plus you should subtract from that the surrogates, which are not legal for open interchange due to the UTF flaw, but must be supported inside your program.
