International Components for Unicode (ICU) is an open-source project of mature C/C++ and Java libraries for Unicode support, software internationalization, and software globalization. ICU is widely portable to many operating systems and environments. It gives applications the same results on all platforms and between C, C++, and Java software.
A "character" may use any number of Unicode code points. [20] For instance an emoji flag character takes 8 bytes, since it is "constructed from a pair of Unicode scalar values" [21] (and those values are outside the BMP and require 4 bytes each). UTF-16 in no way assists in "counting characters" or in "measuring the width of a string".
iconv – a program and standardized API to convert encodings; luit – a program that converts encoding of input and output to programs running interactively; International Components for Unicode – A set of C and Java libraries to perform charset conversion. uconv can be used from ICU4C. Windows: Encoding.Convert – .NET API [15]
Converts Unicode character codes, always given in hexadecimal, to their UTF-8 or UTF-16 representation in upper-case hex or decimal. Can also reverse this for UTF-8. The UTF-16 form will accept and pass through unpaired surrogates e.g. {{#invoke:Unicode convert|getUTF8|D835}} → D835.
The Standard Compression Scheme for Unicode (SCSU) [1] is a Unicode Technical Standard for reducing the number of bytes needed to represent Unicode text, especially if that text uses mostly characters from one or a small number of per-language character blocks. It does so by dynamically mapping values in the range 128–255 to offsets within ...
[a] The prevalence of string handling using this logic means that, even in the context of UTF-16 systems such as Windows and Java, UTF-16 text files are not commonly used. Rather, older 8-bit encodings such as ASCII or ISO-8859-1 are still used, forgoing Unicode support entirely, or UTF-8 is used for Unicode.
UTF-8 is the only encoding of Unicode (explicitly) listed there, and the rest only provide subsets of Unicode. The ASCII-only figure includes all web pages that only contain ASCII characters, regardless of the declared header.
This 7-bit encoding allows the transport of texts consisting of printable characters from Basic Latin (Unicode block) (with the exception of the grave accent/backtick), as well as some characters of the ISO Latin 1 character set. It also allows the encoding of texts written in the Greek script, but only capitals; for such use in Greek, the ...
