Bug ID: 405272
Summary: KTextEditor: column count wrong for UTF32
Product: frameworks-ktexteditor
Version: unspecified
Platform: Other
OS: All
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: kwrite-bugs-n...@kde.org
Reporter: rjvber...@gmail.com
Target Milestone: ---

Sample document
SUMMARY
Certain emojis have a UTF32 representation and when these appear in text they
are counted as 2 characters, leading to invalid column counts.
STEPS TO REPRODUCE
1. Open the attached document in kwrite or kate, advance the cursor over
individual lines
OBSERVED RESULT
The column counter in the status bar jumps from 1 to 3 advancing the cursor 1
character to the right from the beginning of lines that start with a UTF32
glyph
EXPECTED RESULT
Such glyphs show as a single glyph and the cursor behaves that way too (= a
single left/right press is sufficient to move over them). The counter should
behave the same way.
Tested on Mac OS X but I have no reason to suspect this would be any different
on other platforms.
