Subject: added logging to the font converter
X-Git-Tag: Alt-Design-integration-base~426
X-Git-Url: https://source.dussan.org/?a=commitdiff_plain;h=ba2073f0cad9bb7cf1c82186f595bb7c0afbffef;p=xmlgraphics-fop.git

added logging to the font converter
fixed (possibly) a problem where certain fonts
had a range value for the last character causing it to try to get invalid info
also handles the lack of support for non-unicode cmap tables better
