Dear Volga,

To make sure we're focusing on the bugs that affect our users today,
LibreOffice QA is asking bug reporters and confirmers to retest open, confirmed
bugs which have not been touched for over a year.

There have been thousands of bug fixes and commits since anyone checked on this
bug report. During that time, it's possible that the bug has been fixed, or the
details of the problem have changed. We'd really appreciate your help in
getting confirmation that the bug is still present.

If you have time, please do the following:

Test to see if the bug is still present with the latest version of LibreOffice
from https://www.libreoffice.org/download/

If the bug is present, please leave a comment that includes the information
from Help - About LibreOffice.

If the bug is NOT present, please set the bug's Status field to
RESOLVED-WORKSFORME and leave a comment that includes the information from Help
- About LibreOffice.

Please DO NOT

Update the version field
Reply via email (please reply directly on the bug tracker)
Set the bug's Status field to RESOLVED - FIXED (this status has a particular
meaning that is not 
appropriate in this case)


If you want to do more to help you can test to see if your issue is a
REGRESSION. To do so:
1. Download and install oldest version of LibreOffice (usually 3.3 unless your
bug pertains to a feature added after 3.3) from
https://downloadarchive.documentfoundation.org/libreoffice/old/

2. Test your bug
3. Leave a comment with your results.
4a. If the bug was present with 3.3 - set version to 'inherited from OOo';
4b. If the bug was not present in 3.3 - add 'regression' to keyword


Feel free to come ask questions or to say hello in our QA chat:

Thank you for helping us make LibreOffice even better for everyone!

Warm Regards,
QA Team

Possibly, I’m not 100% sure this is what is going on.

--- Comment #7 from Khaled Hosny  ---
I don’t this is a font fallback issue since our HarfBuzz-based font fallback
code certainly handles this (i.e. does not require control characters to be
present in the font). I suspect the issue is happening at a higher level when
we decide if a character should use Western/CTL/CJK font.

Yes, the usage of BiDi characters should be used for controlling text
direction, and just set costomized direction within text, not affect font
rendering for surrounding text.

Hi,

If I understand it correctly, that's because the RTL text "空航南海" here is
identified as CTL Text, rather than East Asian Text. (Move the cursor to the
text, and check the status bar.)

Therefore, it's using the font set for CTL Text (Format -> Character -> CTL
font).

I tested again, if I selest the who text, then set the font to "仿宋", it works,
but if I set different font face for Western Text Font and Asian Text Font, the
problem appearing to me.

Do you mean setting same CJK font face to the two "海南航空"?
I tried to set both of them to "思源宋体 CN Medium", they are displaying correctly
as this font. 
I also tried "仿宋", it works.

Am I doing right? If I am doing right, this may be tested by someone else on
Windows.
