Hi there,
triggered by the recent questions about sorting, I started digging into my
problems with upper('ä')='ä' when using LC_CTYPE and LANG = de_DE.UTF-8.
I have checked with Java (toUpperCase()) and C (see attached program, might
help others) that my locale is working, but postgres (initdb and postmaster
running with LANG=de_DE.utf8, -E UNICODE) still insists that upper('ä')
equals 'ä'. What else can be wrong?
Mit freundlichem Gruß / With kind regards

fprintf(stderr, "Can't set the specified locale! "
"Check LANG, LC_CTYPE, LC_ALL.\n");
return 1;
}
wchar_t* text = L"ä";
printf( "is: towupper(%x) = %x\n", text[0], towupper(text[0]) );
return 0;
}
