When writing in Hebrew or Arabic, LO identifies those languages as Hindi for purposes of spelling check (at the bottom of the screen). Trying to manually change that through the menu that opens up when pressing on the language choice shows that Hebrew/Arabic are detected, but clicking on them instantly reverts to Hindi. Only way I found around it was to change the CTL language, but even that seems to not work for anyone who deals with multi-lingual setups (say, people who write Arabic, Hebrew and English at the same time).
This is almost identical to bug 108151, except for being about a different language (or rather script) group than the DE/OS default. The underlying cause is also likely the same, as it is also reproducible on Linux: Version: 26.8.0.0.alpha0+ (X86_64) Build ID: e128b33c37487f5c1df45cd0ab2ec8a70dcec209 CPU threads: 4; OS: Linux 6.12; UI render: default; VCL: gtk3 Locale: en-IL (en_IL); UI: en-US but not on Windows, with a recent 26.8 nightly. So, the underlying cause is likely also the same. Marking as a dupe, but - if you believe there is significant enough difference, feel free to reopen and explain. *** This bug has been marked as a duplicate of bug 108151 ***
