patch waiting for review here: https://gerrit.libreoffice.org/c/core/+/197304
Quoting Karia's comment from Jenkins: "The Ol Chiki script (Santali script) is generally not considered a CTL script. Because it functions as a simple alphabetic layout, similar to Latin, with no contextual shaping or reordering required by the script itself." See https://gerrit.libreoffice.org/c/core/+/197304
Sorry for not being clear earlier. The Santali language is written in two forms using the Ol Chiki script: Chhapa (Santali for 'print'): Used for publications. Usaraà (Santali for 'quick'): A cursive style mainly for handwriting, traditionally limited to pen and paper—though digital Usaraà typefaces now exist. (Ref:https://en.wikipedia.org/wiki/Ol_Chiki_script#Print_and_cursive_styles ; Image of Chhapa and Usaraà: https://en.wikipedia.org/wiki/Ol_Chiki_script#/media/File:Ol_chiki_cursive.png) Unfortunately, the cursive Usaraà variants are not yet included in the Unicode Ol Chiki block. Key differences include the ahad diacritic, which in print style combines with ᱜ, ᱡ, ᱦ, ᱫ, and ᱵ. In cursive, these can form ligatures with ᱽ. Unicode may add them in the future. Long-term, treating Ol Chiki as a CTL script would better support these behaviors.
Just for the record, I abandoned the patch.
I am not an expert, so I asked ChatGPT. I was told that Santali (Ol Chiki) should be placed under CTL / Complex Script / Indic Script categories, not under "simple" or "Latin-like" scripts.
