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.

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?
Comment 11 dante19031999 2020-11-12 22:52:17 UTC
The bug is real. Lo has no &HEX; support for mathml. Only accepts unicode first character of the string.

Dante: let's put this one to ASSIGNED since you assigned yourself.
