There were two ways of implementing mathbb and script (mathcal).
First
way: using additional font, faking the double stroke and sacript
characters (easy way). LO gains a default font for double stroke and
script.
Second way: analyze the code in the brackets and
apply to TVARIABLE and TTEXT nodes a transformation table of symbols
(find and replace all of them until the next font change, probably the
best point to implement are the nodes). This option requires more
processing, and also may be difficult since LO utf chasers are int16 and
some chars as U+1D54F 𝕏 may be a little problematic. As well there
are missing symbols on open symbol such as U+1D54F which would need to
be implemented.
Pros of first way: easy and fast, no additional computing required. Everything goes on double stroke.
Pros
second way: allows to choose, possibility of latex imitations and does
not close the door to that simple latex editor there's proposed on the
wiki.
Those changes will also be an opportunity to update
mathml, since there are TODOs in this matter and debug it a bit (already
working on it).
For the answers I get it's the second way we are taking and will mark gerrit
97084
as abandoned in the near future. But this will take time, so I ask for
patience. The other point is I have no idea of making fonts, I will code
everything as if the font was updated, but I'm gonna need help with the
open symbol stuff. And also, if you know how to deal with the overflow
with unicode chars with chars like U+1D54F, please let me know.

In principle, those fonts would be SIL OFL, so not a blocker for
Debian.
Extra size matters of course, so just to close this discussion here
for the moment: Regina & Dante are working on extending OpenSymbol
instead.
