Description Karsten Müller 2020-07-06 12:47:47 UTC
Description:
Hi,
I have a problem with font rendering (in this case: TechnicBold font).

Steps to Reproduce:
When I'm formatting a text/char using this font (TechnicBold), the presentation on screen/ printer/ pdf is wrong.
If I "build" the same text using the "insert special char" functionality, the text is displayed correct.
It is the same behaviour in all LO modules (Writer, Draw, ...)
It makes no difference if OpenGL is active or not.

Actual Results:
Textformatting is displayed wrong

Expected Results:
Correct formatting without any workaround


Reproducible: Always


User Profile Reset: No

Opened with FontForge, the proprietary/copyright font in attachment 163440 [details] is incomplete and incorrectly mapped from PUA and not otherwise a Symbol file (which it may have been to start). 

In short it is unusable in LibreOffice, but could be modified and remapped by a user (with license rights) to be made individually functional.

@Khaled, wait is this another instance of bug 122836 against HarfBuzz?

https://github.com/harfbuzz/harfbuzz/issues/1918

wasn't https://github.com/harfbuzz/harfbuzz/commit/d304d60e4d49df14ed85d6646680085f27bafbf2 supposed to fix intended cmap Symbol use?
