International character support in text formatting
You can use text formatting commands to work with text composed of the international extended character set used for European languages.
The international extended character set provides the characters and symbols used in many European languages, as well as an ASCII subset composed of English-language characters, digits, and punctuation.
All characters in the European extended character set have ASCII forms. These forms can be used to represent the extended characters in input, or the characters can be entered directly with a device such as a keyboard that supports the European extended characters.
The following text-formatting commands support all international languages that use single-byte characters. These commands are located in /usr/bin. (The commands identified with an asterisk (*) support text processing for multibyte languages.
