Currently + this script can only generate Big Endian (Network Byte Order) .cct files. + This decreases conversion performance on little endian systems since iconv + library needs to swap all bytes that it reads from loaded CCS table. + Something such -LE and -BE options should be added to 'iconv_mktbl' script. + + Also, we can keep two .cct file versions - BE and LE (e.g., koi8_r-le.cct + and koi8_r-be.cct) and iconv library will automatically choose needed cct. + + Or we can keep both LE and BE data in one .cct file. + +2. http://www.dante.net/staff/konstantin/FreeBSD/iconv/ contains additional + CES and CCS converters (see iconv-extra-2.0.tar.gz and + iconv-rfc1345-2.0.tar.gz). These extra converters should be added too. + +3. Documentation should be created. It should contain: + 1) How to compile iconv (configure script options description) + 2) How to add new converter + 3) Work principles. + It would be nice if iconv architecture will be described too. + +4. CCS files loading (iconv/lib/loaddata.c). Now file is loaded into memory + for every iconv descriptor. For example, if one use two iconv descriptors + for UTF8->KOI8-R and UTF-16->KOI8-R conversions, koi8_r.cct file will + be loaded twice. To save memory, we should load each .cct only once + (if possible). + + Artem B. Bityuckiy, + SoftMine Corporation, + <abitytsky@softminecorp.com>, + <dedekind@mail.ru>, + Jan, 2004. |
