This isn't really an answer to your question, but it might be a 
workaround:  switch to the UTF-8 encoding.  It is the default on many 
systems (e.g. most Unix-alikes these days), so it is probably better 
supported internally.  You might need to convert your string to UTF8; 
you can do that by replacing

'pučina (open-sea)'


with

'pu\u010dina (open-sea)'
