Special character when reading data from file .sdf

It is codepage problem.

I have this two function to convert special characters from NAV to file, and from file to NAV.
But it works in Croatia.

Best way to do is to save file from SQL with one string conatining special characters ČŠĐŽ...
ŽImport it and then you parse it to int like:

i ineteger

i:=incomeText[1]; //supose first leter is Č

MESSAGE('%1',i); Then you know that char code you must replace with Č



My funtioncs:

FromFileToNAV(inText : Text[500]) outText : Text[500]
NasiZnaci[1]:=138; //equals to Š in from file
NasiZnaci[2]:=208; // equals to Đ in from file
NasiZnaci[3]:=200; //...
NasiZnaci[4]:=198;
NasiZnaci[5]:=142;
NasiZnaci[6]:=154;
NasiZnaci[7]:=240;
NasiZnaci[8]:=232;
NasiZnaci[9]:=230;
NasiZnaci[10]:=158;
outText:=CONVERTSTR(inText,NasiZnaci,'ŠĐČĆŽšđčćž');


second function:

FromNAVtoFile(inText : Text[500]) outText : Text[500]
NasiZnaci[1]:=138;
NasiZnaci[2]:=208;
NasiZnaci[3]:=200;
NasiZnaci[4]:=198;
NasiZnaci[5]:=142;
NasiZnaci[6]:=154;
NasiZnaci[7]:=240;
NasiZnaci[8]:=232;
NasiZnaci[9]:=230;
NasiZnaci[10]:=158;
outText:=CONVERTSTR(inText,'ŠĐČĆŽšđčćž',NasiZnaci);

I also found on problem where inbound files where in unicode format, where spectial charters where compaund of 2 bytes, then you must parse stirng by 2 to 2 bytes and try to find combinations. If you could uplad file maybe i can help.
