When using a Spanish keyboard, the "composed characters" disappear when using the syntax highlighting.
NB: Spanish keyboards (as Catalan, and other ones) have the "compose characters" option, meaning that you create accented characters by clicking the "accent" key first, then the "character" key. E.g. `+ o = ò
What happens to me is that such characters sometimes disappear right after clicking on the second key.
Steps to Reproduce:
- Open any page in edit mode
- Write a "composed character", e.g. è
- It randomly disappears!
- Should write the accented character.
