does FOP support characters defined in a cmap_format_12 font table?

Hi,

I'm trying to find a font that supports 𐌃, or Unicode Character 'OLD 
ITALIC LETTER DE' (U+10303). This should be available in the "Noto Sans 
Old Italic" font (https://www.google.com/get/noto/#sans-ital).

Yet, even though I successfully register the font in a fop configuration 
file, FOP-2.2 reports following warnings:

   INFO: Default page-width set to: 8.26in
   nov 28, 2017 4:37:49 PM org.apache.fop.fo.properties.CommonHyphenation getHyphChar
   WARNING: Substituted specified hyphenation character (0x2d) with 0x20 because the font doesn't have the specified hyphenation character: NotoSansOldItalic,normal,400
   nov 28, 2017 4:37:50 PM org.apache.fop.events.LoggingEventListener processEvent
   WARNING: Glyph "?" (0xd800) not available in font "NotoSansOldItalic".
   nov 28, 2017 4:37:50 PM org.apache.fop.events.LoggingEventListener processEvent
   WARNING: Glyph "?" (0xdf03) not available in font "NotoSansOldItalic".
   nov 28, 2017 4:37:50 PM org.apache.fop.events.LoggingEventListener processEvent
   INFO: Rendered page #1.

When inspecting the PDF file, instead of the character (ideally), or the 
substitution character # (fallback), I see "ï¿¿ï¿¿". Minimal XSL-FO test 
file and output PDF file attached.

When inspecting the Noto Sans Old Italic CMAP tables via the fonttools 
Python library (https://github.com/fonttools/fonttools), I noticed that 
the character is mapped in the "cmap_format_12" table. I'll attach the 
TTX XML representation of this font, generated via fonttools.

Now, given that I have successfully registered a font (Noto Sans Old 
Italic) which allegedly supports this character (OLD ITALIC LETTER DE), 
what else should I do in order to make FOP output the actual character?

Kind regards,

Ron

That's a reasonable request.

Thanks for pointing this out. From that issue thread, I gather this 
won't be resolved in the near future.

Perhaps it's worth, then, pointing this out in the documentation 
(https://xmlgraphics.apache.org/fop/2.2/fonts.html) so users won't get 
false expectations when trying to find suitable fonts for characters 
that eventually are unsupported by FOP?

Kind regards,

Ron

Characters outside the BMP are not yet supported by FOP. See [1].

Perhaps I should make clear that this is a general pattern: for all 
characters that are exclusively defined in a font's "cmap_format_12" 
subtable (and that don't also occur in a "cmap_format_4" subtable), FOP 
reports these as non available.

Is this a limitation or bug in FOP, or my misundertanding of how to use 
such characters?

Best,

Ron
