Bug: cursor position incorrect when entering 'combining diacritical marks' or Thai script

[windwerfer]

expected: cursor position after entering a normal and a combing char: 1 char shifted

what happens: cursor moves 2 positions

result: the cursor position is off for all following char in that line (if there are a lot of combining char it becomes very hard to edit text without trying out at wich place the actual cursor position is)

to replicate copy the following lines h̅ type h + u+305
or in asian langages (eg Thai) ก้ type ก + ้ (u+e01 + u+e49)

a more extreme example (cusor is off by about 7 char at the end of the line) แม้ว่าชาวเน็ตจะไม่สนใจมองผ่านเมื่อตอนแรกๆ

ps thank you very much for the hard work. i really like this editor.

Can you share a test file so I can test it myself?

[windwerfer]

thanks for the quick reply, here a test file. https://drive.barthoptik.de/diacritics.txt

its not much to see, but when you place the cursor at the last line, last char (tab on the screen) you can still move to the left with the arrow keys. than press any letter an it will apear in the wrong place.
