            Bug ID: 138966
           Summary: Version 7.0.3.1 does not attach diacritics when we use
                    Insert Special Character for Sanskrit Devanagari fonts
           Product: LibreOffice
           Version: 7.0.3.1 release
          Hardware: All
                OS: Windows (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Writer
          Assignee: libreoffice-bugs at lists.freedesktop.org

Description:
When we use LibreOffice 7.0.3.1 to type Sanskrit text, the Geometric Shape
dotted circle $25CC always gets inserted. The Mark diacritic is not attached to
the Base glyph.

1. This happens when we use Insert Special Character.
Since Sanskrit has a large number of diacritic marks, vowels, etc. that is the
only way to completely input a page of Sanskrit text.

2. It does not happen if we use a special keyboard IME that contains the
diacritics and we type the base glyph and the mark glyph, without having to use
Insert Special Character.

3. This issue was not present in LibreOffice 6.4.7.2
4. After the upgrade to 7.0.3.1, we can no longer type legitimate Sanskrit
text.

Steps to Reproduce:
1. Insert क Unicode $0915
2. Insert ा Unicode $093E
3. The result got is क ा instead of का

Actual Results:
$0915 + $25CC + $093E

Expected Results:
$0915 + $093E



Reproducible: Always


User Profile Reset: Yes


OpenGL enabled: Yes

Additional Info:
1. Since $0915 is defined as a Base glyph and $093E is a Mark, it should get
attached without the INVALID combining symbol intervening.

2. Only a single glyph is mentioned here. However the problem is with any and
all combinations of Base and Mark diacritics in Sanskrit.

3. This issue is not present in 6.4.7.2 and that is working excellently.

4. In 7.0.3.1 it gets attached when we use a Sanskrit IME keyboard that
contains both $0915 and $093E.
