I assume UnicodeLib handles - these, but can't be sure. - C99 / JAVA - well, yes. - - -Iconv Module: -============= - -The iconv module is effectively a thin veneer around UnicodeLib. However, -8bit encodings are implemented within the module rather than using the -support in UnicodeLib. The rationale for this is simply that, although -UnicodeLib will understand (and act upon - reportedly...) additions to -the ISO2022 Unicode resource, other encodings are ignored. As the vast -majority of outstanding encodings fall into this category, and the code -is fairly simple, it made sense to implement it within the module. - -With use of the iconv module, the list of outstanding encodings is -reduced to: - - CP1255 (requires state-based transcoding) - - GB18030 (not 8bit - reportedly a requirement of PRC) - HZ-GB-2312 (not 8bit - supported by IE4) - - CP950 (not 8bit - a (MS) variant of Big5) - BIG5-HKSCS (not 8bit - again, a Big5 variant) - - CP949 (not 8bit) - - ARMSCII-8 (easily implemented, if required) - - VISCII (easily implemented, if required) - CP1258, TCVN (requires state-based transcoding) - -Additionally, the rest of the CodePage encodings implemented in iconv -but not listed above (due to omissions from the iconv documentation) -are implemented by the iconv module. |
