1 NOTE: Code downloaded from http://www.unicode.org 2 3 The accompanying C source code file "ConvertUTF.c" and the associated header 4 file "ConvertUTF.h" provide for conversion between various transformation 5 formats of Unicode characters. The following conversions are supported: 6 7 UTF-32 to UTF-16 8 UTF-32 to UTF-8 9 UTF-16 to UTF-32 10 UTF-16 to UTF-8 11 UTF-8 to UTF-16 12 UTF-8 to UTF-32 13 14 In addition, there is a test harness which runs various tests. 15 16 The files "CVTUTF7.C" and "CVTUTF7.H" are for archival and historical purposes 17 only. They have not been updated to Unicode 3.0 or later and should be 18 considered obsolescent. "CVTUTF7.C" contains two functions that can convert 19 between UCS2 (i.e., the BMP characters only) and UTF-7. Surrogates are 20 not supported, the code has not been tested, and should be considered 21 unsuitable for general purpose use. 22 23 Please submit any bug reports about these programs here: 24 25 http://www.unicode.org/unicode/reporting.html 26 27 Version 1.0: initial version. 28 29 Version 1.1: corrected some minor problems; added stricter checks. 30 31 Version 1.2: corrected switch statements associated with "extraBytesToRead" 32 in 4 & 5 byte cases, in functions for conversion from UTF8. 33 Note: formally, the 4 & 5 byte cases are illegal in the latest 34 UTF8, but the table and this code has always catered for those, 35 cases since at one time they were legal. 36 37 Version 1.3: Updated UTF-8 legality check; 38 updated to use UNI_MAX_LEGAL_UTF32 in UTF-32 conversions 39 Updated UTF-8 legality tests in harness.c 40 41 42 Last update: October 19, 2004 43 44 45
