0. do not escape Unicode Greek letters via LaTeX math mark-up: pass them
through un-modified to LaTeX document,
1. if "fontenc" receives extra option LGR, then pdflatex will support
Unicode Greek letters (not in math), and with extra option T2A it
will support (most) Unicode Cyrillic letters.
2. for pdflatex with LGR, this will use "textalpha" LaTeX package and
"substitutefont" package to set up some automatic font substitution
to work around the unavailability of Greek with "times"
package (which is default font package chosen by Sphinx for
pdflatex), same with T2A and "substitutefont" for Cyrillic.
3. for xelatex/lualatex, set up Computer Modern Unicode as default font,
as it supports Cyrillic and Greek scripts,
4. for platex, don't do anything special as the engine already has
its default font supporting Cyrillic and Greek (even in math mode!)
Closes: #5251
Fixes: #5248
Fixes: #5247
- Reuse jsload() in all tests to reduce duplication.
- Fix -2 index to -1, to include the entire JSON string. Was previously
chopping off the final '}'.
- Assert the serialized string ends with a closing parenthesis
Code should not arbitrarily mix bytes & str values. The values should be
understood and deliberate. When Python is run with the -b option, this
change fixes warnings of the form:
BytesWarning: str() on a bytes instance
In the Python 3 only code base, this function is no longer necessary.
The type of values is well understood and deliberate. Code should avoid
arbitrary mixing of bytes & str.
By removing force_decode() calls from docstring values, can deprecate
the now unused 'encoding' arguments to various autodoc methods.

Since tox-3.2.0, 'usedevelop' option and 'deps=.[test,websupport]'
option have been conflicted. As a workaround, this adds
'install_command' option to avoid the situation.
