Which is the same.
1 character = wchar_t = wxChar = wxWChar in Unicode,
1 character = char = wxChar in non-Unicode.
Anyhow, having a deeper look at wx unicode conversions it seems that (in
contrast to earlier versions) now utf-conversions are supported in
non-unicode too, making that offending line more than a no-op.
Unfortunately, the usage of wxStringBuffer as argument to MB2WC is
*plain wrong*, because writing wchar_t to char is pure bullsh*t for
non-unicode. The code assumes wxChar==wchar_t, which is true in unicode
only.
Which condenses down to "utffile.cpp is not non-unicode compatible".
I've added a #error accordingly. Until utffile is thoroughly reworked
for non-unicode, compiling pgadmin in unicode mode is *required*.
Regards,
Andreas
