--- Comment #10 from Georg Müller <georg.mueller at private.m2tech.de> ---
If I may make a suggestion, I would recommend to drop the OpenSymbol font for
Math. It supports almost no symbols and does not even provide a regular
alphabet. I created an Writer document to compare the font with several
alternative and for me it seams, that almost all other fonts which are either
common in Linux or in Latex provide much more characters much much more
persistence in design of the characters including symbols.

The Latex Font Computer Modern provides many different typefaces (I tested
Roman Serif and Roman Sans Serif) and a lot of symbols. Even the standard font
Liberation Serif supports more characters, but has lacks of special symbols
like arrows with strokes like U+219A, U+219B and U+21AE.

I tested also Open Sans, MathJax_Math and Ubuntu. Regarding to regular letters
Computer Modern seams unbeatable in formulas, but if one is just thinking of
symbols, there are many free alternatives, that provide much more UTF-8
characters than OpenSymbol. Please consider to change the math symbol font for
a more state of the art font with more characters and more persistence.

A few questions:

1) Can one remap the characters without compiling LibreOffice?
2) In the linked issue was an comment about changing the font in 
/usr/share/fonts/truetype/openoffice/opens___.ttf
For me this didn't work. I restarted LibreOffice, but the applied font was the
same. I don't know, if this font in that location is just used as fallback, but
would be nice if you have any idea, how I could change that font or as I asked
to change even the mapping including the font.
