Use case or problem
Obsidian doesn’t provide up-to-date French spell checking, it provides the same shitty one that Google didn’t care enough to update (Chromium issue number 403772455); and doesn’t provide one for Esperanto.
In practice, that means I disable spell checking because it’s unusable in my use case, which is a bit annoying considering it’s an app I use for writing.
Proposed solution
Allow me one way or another to use the system provided spell checking dictionaries under Linux, be it the Hunspell or .bdic ones.
Current workaround (optional)
I installed dictionaries (including one Estonian that will serve for Esperanto instead) and I do (I’m on Arch Linux):
ln -s /usr/share/qt6/qtwebengine_dictionaries/en_US.bdic ~/.config/obsidian/Dictionaries/en-US-10-1.bdic
ln -s /usr/share/qt6/qtwebengine_dictionaries/fr_FR.bdic ~/.config/obsidian/Dictionaries/fr-FR-3-0.bdic
ln -s /usr/share/qt6/qtwebengine_dictionaries/de_DE.bdic ~/.config/obsidian/Dictionaries/de-DE-3-0.bdic
ln -s /usr/share/qt6/qtwebengine_dictionaries/eo.bdic ~/.config/obsidian/Dictionaries/et-EE-3-0.bdic
Then restart Obsidian. I have no idea how well it’ll survive updates (I suppose 3-0 and 10-1 are version numbers?).
