ExtTextOutW record with Aleph/Bet/Gimel/Dalet has ETO_GLYPH_INDEX set.

As per [MS-EMF] spec:
"This bit indicates that the codes for characters in an output text string are indexes of the character glyphs in a TrueType font.
Glyph indexes are font-specific, so to display the correct characters on playback,
the font that is used MUST be identical to the font used to generate the indexes."

That could be probably supported by using HarfBuzz' hb_font_glyph_to_string() or FreeType's FT_Get_Glyph_Name() to "convert encoding".

(Kudos to Behdad for pointing to the right APIs).

Dear Ofir,

To make sure we're focusing on the bugs that affect our users today, LibreOffice QA is asking bug reporters and confirmers to retest open, confirmed bugs which have not been touched for over a year.

There have been thousands of bug fixes and commits since anyone checked on this bug report. During that time, it's possible that the bug has been fixed, or the details of the problem have changed. We'd really appreciate your help in getting confirmation that the bug is still present.

If you have time, please do the following:

Test to see if the bug is still present with the latest version of LibreOffice from https://www.libreoffice.org/download/

If the bug is present, please leave a comment that includes the information from Help - About LibreOffice.
If the bug is NOT present, please set the bug's Status field to RESOLVED-WORKSFORME and leave a comment that includes the information from Help - About LibreOffice.

Please DO NOT

Update the version field
Reply via email (please reply directly on the bug tracker)
Set the bug's Status field to RESOLVED - FIXED (this status has a particular meaning that is not 
appropriate in this case)

If you want to do more to help you can test to see if your issue is a REGRESSION. To do so:
1. Download and install oldest version of LibreOffice (usually 3.3 unless your bug pertains to a feature added after 3.3) from https://downloadarchive.documentfoundation.org/libreoffice/old/

2. Test your bug
3. Leave a comment with your results.
4a. If the bug was present with 3.3 - set version to 'inherited from OOo';
4b. If the bug was not present in 3.3 - add 'regression' to keyword
