Greetings,

This issue is making my head flat from pounding it against the wall.  It appears to be a bug in Cygwin 1.7, but I can't say with any certainty.  I've been down too many dead end trails already...

With cygwin 1.7.5, file name with a special characters such as ñ (n with tidle above it) fail be properly extracted from a WIN32_FIND_DATA structure with findFirstFile (or findNextFile).

To set up a simple test scenario, I created a file in C:\Testing named  Mañana.docx.  I compiled the code at the end of this message on Cygwin 1.7.9 with GCC version 3.4.4.

On the Cygwin 1.7.9 machine, it returns:
$ ./winfilestat3.exe
hFind filename is ***Ma▒ana.docx***
hFind file name stat return code is: -1
character 0 is M
character 0 is  signed int 77, hex 4d
character 1 is a
character 1 is  signed int 97, hex 61
character 2 is ▒
character 2 is  signed int -15, hex fffffff1
character 3 is a
character 3 is  signed int 97, hex 61
character 4 is n
character 4 is  signed int 110, hex 6e
character 5 is a
character 5 is  signed int 97, hex 61
character 6 is .
character 6 is  signed int 46, hex 2e
character 7 is d
character 7 is  signed int 100, hex 64
character 8 is o
character 8 is  signed int 111, hex 6f
character 9 is c
character 9 is  signed int 99, hex 63

NOTE that the ñ is interpreted as ▒, and the stat fails.

I moved the compiled program to another PC running Cygwin 1.5.25.  It CORRECTLY returns:
bash-3.2$ ./winfilestat3.exe
hFind filename is ***Mañana.docx***
hFind file name stat return code is: 0
character 0 is M
character 0 is  signed int 77, hex 4d
character 1 is a
character 1 is  signed int 97, hex 61
character 2 is ñ
character 2 is  signed int -15, hex fffffff1
character 3 is a
character 3 is  signed int 97, hex 61
character 4 is n
character 4 is  signed int 110, hex 6e
character 5 is a
character 5 is  signed int 97, hex 61
character 6 is .
character 6 is  signed int 46, hex 2e
bash-3.2$ 

Note the ñ is correct, and the stat succeeds.

Is this a bug, or do I need to set something up special on Cygwin 1.7 to get it to work the way it used to?

Thanks in advance,
Leon
