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.
Hexadecimal Unicode input can be enabled by adding a string type (REG_SZ) value called EnableHexNumpad to the registry key HKEY_CURRENT_USER\Control Panel\Input Method and assigning the value data 1 to it. Users will need to log off and back in after editing the registry for this input method to start working.
In Unicode, the implicit directional mark characters are encoded at U+061C ARABIC LETTER MARK, U+200E LEFT-TO-RIGHT MARK (‎) and U+200F RIGHT-TO-LEFT MARK (‏). In UTF-8 these are D8 9C, E2 80 8E and E2 80 8F respectively. Usage is prescribed in the Unicode Bidirectional Algorithm. [1]
For example, the null character (U+0000 NULL) is used in C-programming application environments to indicate the end of a string of characters. In this way, these programs only require a single starting memory address for a string (as opposed to a starting address and a length), since the string ends once the program reads the null character.
A numeric character reference refers to a character by its Universal Character Set/Unicode code point, and a character entity reference refers to a character by a predefined name. A numeric character reference uses the format &#nnnn; or &#xhhhh; where nnnn is the code point in decimal form, and hhhh is the code point in hexadecimal form.
A character literal is a type of literal in programming for the representation of a single character's value within the source code of a computer program.. Languages that have a dedicated character data type generally include character literals; these include C, C++, Java, [1] and Visual Basic. [2]
Devanagari is a Unicode block containing characters for writing languages such as Hindi, Marathi, Bodo, Maithili, Sindhi, Nepali, and Sanskrit, among others.In its original incarnation, the code points U+0900..U+0954 were a direct copy of the characters A0-F4 from the 1988 ISCII standard.
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.
