            Bug ID: 125422
           Summary: Diacritic ligatures aren't rendered.
           Product: LibreOffice
           Version: 6.1.5.2 release
          Hardware: All
                OS: Windows (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Writer
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: sentineldraco at gmail.com

Description:
In my font, I have diacritic ligatures that renders the sequence of combining
diacritics differently depending on the order. For example, e + cedilla +
circumflex is rendered as ȩ̂, while e + circumflex + cedilla is rendered as ể.
That might just seems like a fancy feature, but it's actually highly useful in
my linguistics work.
It works everywhere, including in MS Word, but not in LibreOffice Writer, no
matter the settings I've tried. Moreover, all other ligatures works perfectly.
Only the diacritics ones don't.
Moreover, that very exemple (ȩ̂) renders with a weird kerning, the circumflex
gets slightly displaced on the left when the cedilla is added either before or
after, while it renders properly without it. It looks like a bad interaction
between the diacritics (that, I insist, only happens in Libreoffice, that's not
due to my font).

Steps to Reproduce:
1. Have a font with diacritics ligatures.
2. Type the right combination in the right order.
3. Be disappointed.

Actual Results:
No matter the order, the combination is rendered as if the ligature didn't
exist. Plus, with bad kerning that doesn't happen with the diacritics
individually.

Expected Results:
Depending on the order, the diacritics should render differently.


Reproducible: Always
