MtStr The Multext extended string library Claude de Loupy, CNRS

MtStr is a C library for UN*X developed in the context of the MULTEXT project, which extends the usual functions provided in the C character and string ctype and string libraries, in order to accomodate multi-lingual text processing. MtStr is designed especially for texts encoded using SGML. It offers the following capabilities:

• it extends functions such as isupper, strcmp, strtok, etc., to handle several different character sets as well as SGML entities;
• it offers additional functions for translation between different character sets and/or SGML entities;
• it extends functions such as isupper, islower, etc., to handle characters with diacritics;
• it provides means to handle different lexicographic orderings;
• it provides functions for conversion between character classes (e.g., between the accented and unaccented versions of a given character, etc.);
• it handles both fixed-width character sets (in which all characters have the same byte size) and variable-width character sets (in which characters may have different byte sizes);

MtStr internally maps all characters to Unicode/ISO 10646. The functions are table-driven and can therefore be easily customized to handle modification or additional character sets, as needed.
