           Summary: Problem with greek glyphnames using type1 font for
                    postscript output
           Product: Fop
           Version: all
          Platform: PC
        OS/Version: Windows XP
            Status: NEW
          Severity: normal
          Priority: P2
         Component: ps
        AssignedTo: fop-dev@xmlgraphics.apache.org
        ReportedBy: alpapad@gmail.com


We have an issue regarding the generation of postscript documents 
using a custom type1 font in the greek language. The font we tried is 
called kerkis (can be found @ 
http://iris.math.aegean.gr/kerkis/Kerkis_for_LaTeX.zip),
but the same behaviour is observed using true type fonts that we have converted
to type1 using open source tools (like fontforge).

Trying to render the attached sample.fo with the config given, Fop complaints
with the following message:
org.apache.fop.events.LoggingEventListener processEvent WARNING: Glyph "?"
(0x394, Deltagreek) not available in font "Kerkis".
org.apache.fop.events.LoggingEventListener processEvent WARNING: Glyph "O"
(0x3a9, Omegagreek) not available in font "Kerkis".

Our fonts, have glyphs named Omega and Delta - only. Browsing around we found
that basically, the code 0x3a9 is equivalent to 0x2126 (Omega) and 0x394 to
0x2206 (Delta). Apparently there are other codes for the Cyrilic version of
Omega and Delta, that actually "point" to the same glyph. These are all defined
in xmlgraphics-commons library, in org.apache.xmlgraphics.fonts.Glyphs classm
put they point to different glyph names, like:

 Omega;2126
 Omegacyrillic;0460
 Omegagreek;03A9
 Omegaroundcyrillic;047A
 Omegatitlocyrillic;047C

 And
 Delta;2206
 Deltagreek;0394

Fop uses this class to resolve codes to glyph names, and then uses this name to
look the glyph in the font, thus producing the error you see.


The patch fixes the error, what might be missing, is filling the map with a not
found symbol, for the case were no alternatives were found...
