Synopsis
ACE iconv conversion method not working in linux
Description
ACE_TString - convert from default encoding in linux (empty str = UTF-8 as stated in locale cmd) to UTF-32 (which is wchar_t) when the conversion fails - the ACE code defaults to simply adding trailing zeroes - i want iconv to not fail...
Repeat by
use ACE_TString in linux with non-english chars as input (read from xml for example)
Sample fix/ workaround
when you set the from-encoding in the ACE code of iconv_open to UTF-8 instead of empty string (i also recommend to change the "hr" variable there from size_t to signed int - in order to easily check for errors (<0)
