           Summary: formula corrupted on creation in LibO Math (Formula
                    Editor)
          Severity: normal
    Classification: Unclassified
                OS: Linux (All)
          Reporter: [email protected]
          Hardware: x86-64 (AMD64)
            Status: NEW
           Version: 3.6.7.1 rc
         Component: Formula Editor
           Product: LibreOffice

It's possible to get formulas created in Math component (Formula Editor), being
corrupted right at the start: you get corrupted formula at the moment it is
inserted into document.

Such corrupted formula shows as an 'Object Number ...' and does not expose
correct object methods (https://bugs.freedesktop.org/attachment.cgi?id=81029 is
what happens when script trying for those methods finds such formula).

Here's a 100% reproducible recip:

Start from blank, put one "over-64K-codepoint" glyph into it, make formula from
it (I did this with 'Neo Euler-like bold B' glyph U+10FE88 from Asana Math in
my sample). In formula preview the glyph comes out as a 'have no such glyph'
square (the default font in formulas here is Charter).

Now you may save it 'as is', or you may correct the formula source (put
something 100% acceptabel, like ASCII letter), then save. Either way you get a
document with corrupted formula (showing as 'Object #something').

I'm attaching two sample docs, one saved as is
(https://bugs.freedesktop.org/attachment.cgi?id=81582), another corrected
(changed source to 'latin B'), then saved
(https://bugs.freedesktop.org/attachment.cgi?id=81583).
