[cl-gd-devel] CL-GD and LispWorks 5.1: Loading images with extended characters in their pathnames?

[Edi Weitz]

Hi  Chris,

I don't see which of the characters in the file name would not have an
encoding in Latin1.  Is this really the file name you used?

The problem is, though, that UFFI doesn't allow you to specify an
encoding when converting Lisp strings to C strings.  This could
certainly be done in the LispWorks FLI directly and probably (I
haven't looked) in CFFI as well.  A real solution would be to
re-architect CL-GD to use an alternative to UFFI, but I don't have the
time to do it and I haven't used CL-GD for years anyway.

Cheers,
Edi.
