Bug ID: 127902
Summary: Indic: Visarga characters should combine correctly
after Vedic tone markers
Product: LibreOffice
Version: 6.3.2.2 release
Hardware: All
OS: Linux (All)
Status: UNCONFIRMED

Screenshot illustrating bug
Please see the attachment showing the sequence दे॒वेभ्य॑ः. This is created by
latest
LibreOffice 6.3.2 on Kubuntu Bionic LTS. (I do not use Windows so did not test
this there.)
It is observed that there is a dotted circle before the visarga but there
should not be.
The same is observed with other common Devanagari fonts like Noto Sans
Devanagari and Lohit Devanagari. This needs to be fixed.
Reason:
Indic visarga characters are always spacing and placed to the right of the
syllable. Vedic tone markers whether spacing or non-spacing will always be
input before visarga because they apply to the vowel before the visarga.
So the expected sequence is:
syllable + zero or more tone markers + visarga
and so sequences like the example above where the visarga is placed after such
a tone marker should not cause a dotted circle due to cluster breakup.
The file http://www.unicode.org/Public/UNIDATA/IndicSyllabicCategory.txt does
an excellent job of listing the visarga characters and the tone markers under
the sections:
Indic_Syllabic_Category=Visarga
Indic_Syllabic_Category=Cantillation_Mark
