Thank you for your reply. I can indeed change the keyboard layout (Azerty) and switch from the classic layout for French and English to the layout for Hebrew with Tyndale Keyboard and Unicode Font Kits as this is independent of Zettlr. But cursor movement is then not correct:
- in French and English layouts, the cursor moves from left to right and is always to the right of the last letter,
- in Hebrew layouts, the cursor remains totally locked to the left and letters move out of it, each new letter pushing the previous one to the right, so the movement doesn't go from right to left and it's unmanageable.
By comparison, in LibreOffice, there's a menu for changing the writing direction. So when I switch to Hebrew mode, the cursor moves from right to left and is always to the left of the last letter.
On the other hand, it would be useful to be able to change the font to use a more suitable font than the Hebrew characters included in the default font. Perhaps this is possible in css, but I can't see what Markdown-compatible tag you'd need to use to call up fonts and thus change fonts in the same document.
If you can think of any solutions, I'd be happy to try them out!
