Hi Regina,

With the new font file installed, the two harpoon commands results in correctly

Great.


I have tested the new glyph in ordinary text too. I have looked, how it is
placed in other fonts. The solutions vary. "STIX Two Text" puts it over the
character, so that the next character has the same place as if no combined
character is before. "Segoe UI Symbol" puts it half to the right and the next
character tight, so that the harpoon goes into the next character. "Arial
Unicode MS" and "Cambria" puts it entire on the right side and the next
character after the harpoon. That is the same as I see it in OpenSymbol. So now
reason to object.

What is needed, that the new OpenSymbol font is generated during the
build-process?
If you have FontForge (fontforge in PATH) installed, autogen.sh will find it
given --enable-build-opensymbol option, which has been introduced recently:
<https://gerrit.libreoffice.org/#/c/54938/>, and the .ttf will be built.

The export to MathML is OK, import from pure MathML works too.

Tooltips and texts in context menu are OK. But the text in section "Attributes"
in the help needs to be updated. So in case you do not write it yourself, please
add the bug to the "depends on" list in Meta-bug 120200, when your commit your
patch.
Right, I will file an issue once merged.


So for me it looks usable.

In the long term, I would prefer to get a general solution for the MathML
attributes 'accent' and 'stretchy'. But because no one is working on it, I
support to solve this special request in the way you suggest.
I agree with your preference for a general solution, and admit that my patch
is just a one-more-pile thing.

Thank you very much for your throughly inspection.

Cheers,
-- Takeshi Abe
