Description Mike Kaganski 2014-03-09 01:06:54 UTC
Created attachment 95380 [details]
ZIP with problematic MML and screenshot

Importing the MML file from attachment skips some characters.
Seems that they are characters that immediately precede numeric character references (&#xXXXX;).

Also, in the attachment there is a screenshot displaying the current state of import, and the expected result. Problematic places are marked.

Tested with under Win7x64, and under Ubuntu 13.10 x64. Previous versions couldn't handle this file at all.

Marcos, adding you to CC as you suggested in bug 59642, because you are the expert in this area. Please excuse me if it's a wrong thing to do.

Dear Mike Kaganski,

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: https://kiwiirc.com/nextclient/irc.freenode.net/#libreoffice-qa

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

Warm Regards,
QA Team

On pc Debian x86-64 with master sources updated today, I could open second attachment (fa.mml).

About first one which contains f.mml, it displays:
OT instead of italic OM but don't know if it's ok.

Any update here with LO 6.4.5?
