This revives a patch by Uwe and extends it. Additional options to font
packages/fontspec can now be entered in Document Settings.
This is principally also true for TeX fonts, if the new TeXFont tag
MoreOptions is set. For the time being, I have only done this for
MinionPro, as a model and prove of concept.
Note that adding more TeXFonts requires a file format change,
respectively, and changes to tex2lyx (in the same way as I've done for
MinionPro).
This addresses #8226
This is a higher-level (non-TeX) font interface of babel that draws on,
but is supposed to be used rather than, fontspec with babel and XeTeX/
LuaTeX.
File format change.
Addresses: #11614
FWIW this code is important for very old versions of lyx, older than 1.1.5 (released 19 years ago - 2000/06/06).
Funny fact of the day, byte strings do not behave as regular strings in python3 when taking and index.
To get a sub-string we need to pass a range, a integer index will not work as it happens in a regular string:
$ ipython3
...
In [30]: line
Out[30]: b'#This file was created by <mike> Tue Jan 25 10:36:51 2000'
In [31]: line[0]
Out[31]: 35
In [32]: line[0:1]
Out[32]: b'#'
The range notations works for both byte and regular strings in python 3, and it also works in python 2.
Thus the change is simple and effective. In any case I should confess that I was quite surprised by this. :-)

Tested cases are now handled fine.
(There are still many cases where the language support emulation
is too complex for lyx2lyx and manual fixes are required after
lyx2lyx conversion.)
The algorithm in [c9be8bff74b233/lyxgit] did not
account for layout nesting. As a result, some parentheses
were swapped in English text parts
(e.g. around "(for Linux)" in he/Intro.lyx).
In the lines specifying the font, e.g.
\font_typewriter "DejaVuSansMono" "DejaVu Sans Mono"
the system font specs may contain words separated by spaces
If get_containing_layout() finds a layout without name,
it will return an empty string as layoutname.
Calling functions can thus differentiate between missing
\begin_layout and missing layoutname and give a more specific
response or warning.
For some .lyx files with long tables, this fix reduces the
differences in LaTeX export of master, compared to LaTeX export of
the lyx2lyx exported file. Further, this export fixes the lyx2lyx
roundtrip convergence for these cases. For discussion, see:
