The accompanying C source code file "ConvertUTF.c" and the associated header
|
|
file "ConvertUTF.h" provide for conversion between various transformation
|
|
formats of Unicode characters. The following conversions are supported:
|
|
|
|
UTF-32 to UTF-16
|
|
UTF-32 to UTF-8
|
|
UTF-16 to UTF-32
|
|
UTF-16 to UTF-8
|
|
UTF-8 to UTF-16
|
|
UTF-8 to UTF-32
|
|
|
|
In addition, there is a test harness which runs various tests.
|
|
|
|
The files "CVTUTF7.C" and "CVTUTF7.H" are for archival and historical purposes
|
|
only. They have not been updated to Unicode 3.0 or later and should be
|
|
considered obsolescent. "CVTUTF7.C" contains two functions that can convert
|
|
between UCS2 (i.e., the BMP characters only) and UTF-7. Surrogates are
|
|
not supported, the code has not been tested, and should be considered
|
|
unsuitable for general purpose use.

Version 1.0: initial version.
|
|
|
|
Version 1.1: corrected some minor problems; added stricter checks.
|
|
|
|
Version 1.2: corrected switch statements associated with "extraBytesToRead"
|
|
in 4 & 5 byte cases, in functions for conversion from UTF8.
|
|
Note: formally, the 4 & 5 byte cases are illegal in the latest
|
|
UTF8, but the table and this code has always catered for those,
|
|
cases since at one time they were legal.
|
|
|
|
Version 1.3: Updated UTF-8 legality check;
|
|
updated to use UNI_MAX_LEGAL_UTF32 in UTF-32 conversions
|
|
Updated UTF-8 legality tests in harness.c
