Submitted By: Alexander E. Patrakov
Date: 2005-09-30
Initial Package Version: 2.01
Origin: RedHat (but maybe they initially obtained the patch from elsewhere)
Upstream Status: Not applied
Description: Allows one to specify any glibc-supported source charset
for Joliet filenames, instead of the very limited choice offered by mkisofs
itself. Required for writing Windows-readable data CDs in UTF-8 locales when
filenames contain national characters.
