Decoders to display extra character sets in SquirrelMail

[from README.decode] This package contains extra decoding functions.

SquirrelMail decoding functions are used to display and convert messages encoded in different character sets. Extra decoding library provides support of some complex Eastern character sets and some rarely used Apple character sets. Current release supports Big5, Windows-874 cp874, Thai, Windows-949 UHC, Korean, EUC-CN, EUC-JP, EUC-KR, EUC-TW, GB18030, GB2312, ISO-2022-CN, ISO-2022-JP, ISO-2022-JP-2, ISO-2022-KR, Shift_JIS and various x-mac-* character sets.

Extra decoding library can be used in SquirrelMail 1.4.4 or newer. It depends on sq_is8bit function. In order to optimize decoding of Eastern character sets, PHP installation needs recode http// or iconv http// support. Some decoding functions can use mbstring functions present in php 4.3.0. Mbstring decoding needs sq_mb_list_encodings function from SquirrelMail 1.5.1 or 1.4.6.

Some decoding code that be activated only when $aggressive_decoding variable is set to true. This variable should be enabled only on smaller systems, that don’t call aggressive decoding functions very often. Turning on $aggressive_decoding variable by default in packaged SquirrelMail versions is not recommended.
