if I compose message and choose eg. koi8-r charset from menu in the compose
window and the interface is set to iso-8859-1 (NLS::getCharset) then Imp
tries to convert the iso-8859-1 to koi8-r.  String::convertCharset is used
in imp/compose.php to do the charset conversion. String::convertCharset uses
iconv() or mb_convert_encoding(). Iconv() and mb_convert_encoding() mess up
the conversion of from iso-8859-1to koi8-r.

iconv() and mb_convert_encoding() tries to convert input string so that
resulting string have only those characters that are found in both character
sets. This means that if 8-bit character sets are incompatible then most or
all 8-bit characters are lost in conversion.
