Summary: wrongly encoding glyphs after U+10000

https://bugzilla.redhat.com/show_bug.cgi?id=525498

           Summary: wrongly encoding glyphs after U+10000
           Product: Fedora
           Version: rawhide
          Platform: All
        OS/Version: Linux
            Status: NEW
          Severity: medium
          Priority: low
         Component: liberation-fonts
        AssignedTo: cchance(a)redhat.com
        ReportedBy: moyogo(a)gmail.com
         QAContact: extras-qa(a)fedoraproject.org
                CC: petersen(a)redhat.com, cchance(a)redhat.com,
                    fedora-fonts-bugs-list(a)redhat.com,
                    fedora-i18n-bugs(a)redhat.com
   Estimated Hours: 0.0
    Classification: Fedora


Since 1.04 the codepoints U+10000...U+10013 in Liberation Sans,
U+10000...U+1000B in Liberation Serif, and U+10000...U+1000E in Liberation
Mono, are filled with characters that used to be out of bound. The glyph don't
actually match the codepoints.
For example U+10005 LINEAR B SYLLABLE B001 DA is a fraction four in
LiberationSans-Regular.

The error was probably introduced when the font encoding went from Unicode BMP
to Unicode Full.

Would you have any suggestions on the conversion? I have done my best to
preserve that but seems at your feedback it was failed.

Created an attachment (id=363148)
 --> (https://bugzilla.redhat.com/attachment.cgi?id=363148)
path reajusting encodings

The patch does several things:
- clears duplicates of .notdef, .null and nonmarkingreturn
- renames the out-of-bound glyphs to previous names
- adjusts glyph id and references.

Thanks Denis.

Is this patch a proper fix which maintain closer quality with the original TTF
delivered from Ascender?

No, the tables DSIG, hdmx, LTSH and VDMX from the original TTF are not there.

Fontforge can generate a DSIG.
hdmx, LTSH and VDMX are ignored by Fontforge ; they would have to be included
in the generated fonts in post-processing.

As far as I know, no hinting has gone missing and the kern table is the same as
in the original font.
