Description [REDACTED] 2021-09-30 09:44:55 UTC

Description:
In plain text with em spaces, the em space appears at the end of or start of a line instead of being invisible, as normal spaces are. That breaks justified text.

Steps to Reproduce:
1. Enter some text spanning more than one line, format as justified text.
2. Enter an em space (U+2003) at the end of a line, where the text wraps to the next line.
3. The space will be visible at the end or start (in the case where you add a normal space) of the line, instead of serving as a separator of the adjacent words.

Actual Results:
See above.

Expected Results:
Text should wrap correctly, hiding the space at the line break.


Reproducible: Always


User Profile Reset: No



Additional Info:
The wrap code should just treat the em space as a normal space when it is at the end of a line, and only show as an em space in the middle of a line.

Note: Calligra Words treats this correctly, which is why I think this is a bug.

This also happens with all other "space" characters: NO-BREAK SPACE and all those  starting at U+2000 EN QUAD up to U+200C ZERO-WIDTH NON-JOINER.

They all have property "spacing mark" without "joiner" property (to allow for a line break).

I back up the request.

Peter, I've opened attachment 175390 [details] but couldn't see spaces at end or begining of a line. So perhaps the problem has been gone? Could you please retest with the latest version of LibreOffice from https://www.libreoffice.org/download/libreoffice-fresh/ ?

I have set the bug's status to 'NEEDINFO'. Please change it back to 'UNCONFIRMED' if the bug is still present in the latest version.

@Dieter: All em spaces appear in the middle of lines, where they don't do any harm. If you will copy & paste a few words to force an em space to the end of a line, you will see the problem is still there, even in version 7.4.1.2 Snap. Will upload a new sample file.
