** Please read this message in its entirety before responding **

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
http://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

I tested with InDesign 7.5 and there are no rendering problems.

Now i checked the "Space" glyph in the font "Chess Alpha" with FontCreator.

In the "Properties", Register "Mappings" i found this:
Platforms: "Microsoft Symbol"
Encoding format: "Segment mapping to delta values"
And in the mapping table there is a long list of mappings for the glyph:

Value Characte Name
$F020 <$F020>
$F02A <$F02A>
...etc.

Another Chess font, "Chess Berlin" [from the same author] is rendered correctly
by LibreOffice and by OpenOffice
I checked this font with FontCreator, and the only difference i found is, that
in the mapping table for the glyph "Space" there is only ONE mapping:

Value Characte Name
$F020 <$F020>

Now i deleted all mappings in font "Chess Alpha", except the first mapping, and
saved the font under a new name.
After i deletes the original font and replaced it with the modified one,
OpenOffice rendered the white square correctly, but LibreOffice did not.

I'm confused.

I assume AbiWord on Windows is using Uniscribe somehow, so it would be getting
the same rendering as other Windows applications. It would be interesting to
test Firefox/Chrome/InDesign etc. since these have their own layout engines.

I tested the font "Chess Alpha" with the Software AbiWord 2.9.4, no problems
there.

The font is really broken. It provides a symbol “cmap” subtable that does not
have a mapping for space character. Since the font does not support the space
character as far as we are concerned we use a fallback font for it, and it will
most likely have a different width.

I don’t know how other office applications are handling this, one possible
explanation is that they are not doing any font fallback for fonts with symbol
“cmap” subtable, which in turn will cause them to use the glyph for unsupported
characters (glyph 0) which happens to be a white (empty) square in this font.
This also why this font works in Scribus since it does not do any fallback for
missing characters. I tried AbiWord but it gave me similar rendering as
LibreOffice.
