Re: [hatari-devel] Character conversion for filenames in GEMDOS HD emulation

Hello developers,

The GEMDOS HD emulation is really cool and works very well. But currently,

if filenames contain special characters like 'ä', 'ö', 'ü', 'ß', they

are mapped to '@' on the host system and the characters are lost (this

happens for all codes above 128 of the AtariST character set) .

I have written support functions, which convert strings between the AtariST

character set and the Linux (utf-8) and Windows (cp1252) character sets.

extern void Str_AtariToUtf8(const char *source, char *dest);

extern void Str_Utf8ToAtari(const char *source, char *dest, char replacementChar);

extern void Str_AtariToWindows(const char *source, char *dest, char replacementChar);

extern void Str_WindowsToAtari(const char *source, char *dest, char replacementChar);

see https://gist.github.com/1052abb7c6d542f16037

All characters which exist in the target code are mapped correctly. If a 

character does not exist the replacementChar is inserted.

Here is a patch which integrates these functions into Hatari:

https://gist.github.com/a8b0ba0aa6d3bc8adab5

With this patch GEMDOS HD emulation will support all characters which

can be represented on the host system. The patch can be applied by:

patch -p1 --fuzz=3 <../hatari-1.7.0.gemdos.patch

It would be nice if someone who knows the gemdos.c and str.c code well,

could have a look and check if the integration has been done correctly.

Would also be nice if this can be integrated into of the Hatari sources.

Nice idea. Could you add support for user to setup encoding on runtime?
