Sir Alex

Ok, found a way to solve problem. In fact, System module already have crossplatform versions of functions WideCharToMultibyte and MultiByteToWideChar. So functions IcsWcToMb and IcsMbToWc can be easily replaced within: {* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *} function IcsWcToMb(CodePage: LongWord; Flags: Cardinal; WStr: PWideChar; WStrLen: Integer; MbStr: PAnsiChar; MbStrLen: Integer; DefaultChar: PAnsiChar; UsedDefaultChar: PLongBool): Integer; begin Result := LocaleCharsFromUnicode(CodePage, Flags, WStr, WStrLen, MbStr, MbStrLen, DefaultChar, PLongBool(UsedDefaultChar)); end; {* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *} function IcsMbToWc(CodePage: LongWord; Flags: Cardinal; MbStr: PAnsiChar; MbStrLen: Integer; WStr: PWideChar; WStrLen: Integer): Integer; begin Result := UnicodeFromLocaleChars(CodePage, Flags, MbStr, MbStrLen, WStr, WStrLen); end; P.S. Now, MIME decoder works fine

Thank you. It's successfully compiled, so I think v8.70 support Linux. :) Looks like USE_ICONV defined for all non windows platforms, so IcsMbToWc function uses libiconv library for conversion, but something going wrong inside iconv function call...

Hello. I'm just tried to convert our application which uses MIME decoder from OverbyteIcsMimeDec.pas Under Ubuntu I'm got Access Violation (Segmentation fault/Invalid address) in function IcsMbToWc while decoding simple EML file. Problem reproduced by sample code (see below).
