説明

Samba wrapper/stub for iconv character set conversion.

iconv is the XPG2 interface for converting between character encodings. This file provides a Samba wrapper around it, and also a simple reimplementation that is used if the system does not implement iconv.

Samba only works with encodings that are supersets of ASCII: ascii characters like whitespace can be tested for directly, multibyte sequences start with a byte with the high bit set, and strings are terminated by a nul byte.

Note that the only function provided by iconv is conversion between characters. It doesn't directly support operations like uppercasing or comparison. We have to convert to UCS-2 and compare there.
