🍒 KStandardItemListWidget: select by number of unicode chars
Previously during rename, the number of QChar is used for selection, which might be different from number of unicode characters.
Test plan:
- create the file zz
❤ ️❤ ️.txt - rename the file
- verify that the first 4 characters are correctly selected, which didn't work before the patch.
(cherry picked from commit 021365dc)
