Description Bodo Eggert 2021-06-13 17:30:13 UTC
SUMMARY

When unicode characters above 0xffff are copy/pasted into a text, they  disappear. while  I tried to insert the clip before I noticed, kdenlive crashed.

Inserting a unicode character blocks entering values above 0xffff

STEPS TO REPRODUCE
1. copy/paste e.g. a light bulb character (only character in text)
2. save the title clip
3. use the clip

OBSERVED RESULT

kdenlive crashed (won't re-try)

EXPECTED RESULT
A light bulb character

The UTF-16 code ends with 0xffff. All what is bigger then 0xffff is not an official UTF-16 code anymore. See: https://en.wikipedia.org/wiki/UTF-16.

Can we close the issue?
Comment 2 Bodo Eggert 2021-06-23 18:55:43 UTC
Actually UTF-16 goes to U+10FFFF.

https://en.wikipedia.org/wiki/Utf-16#Code_points_from_U+010000_to_U+10FFFF
Comment 3 emohr 2021-06-24 15:29:50 UTC
You are right, and then it's UTF-8. UTF-8 is what I see in the source code.
