Re: Add XeTeX for document building (issue 285790043 by address@hidden)

Reviewers: lemzwerg,

Message:
texinfo.tex's XeTeX support seems have still some issues.

Here's LilyPond PDF documents generated by XeTeX.

I've noticed that non-ascii characters of ``Table of Contents'' are
broken.
Would you review XeTeX generated documents and find other problems?

I'll change Issue 4735, 4736 and 4737 patch status to needs_work.
I won't change status of Issue 4729, 4731, 4732, 4733 and 4734 because
they are no problem.

Already, I've reported the broken TOC issue to bug-texinfo.
http://lists.gnu.org/archive/html/bug-texinfo/2016-01/msg00067.html

It is able to be resolved in LuaTeX.
http://lists.gnu.org/archive/html/bug-texinfo/2016-01/msg00069.html

However, we cannot use LuaTeX that still has another issue.
http://lists.gnu.org/archive/html/bug-texinfo/2016-01/msg00056.html
http://lists.gnu.org/archive/html/bug-texinfo/2016-01/msg00055.html

On the other hands, in XeTeX, it is difficult to solve the broken TOC
issue in a similar way as LuaTeX.

http://lists.gnu.org/archive/html/bug-texinfo/2016-01/msg00071.html

I've created a texinfo.tex's patch for the broken TOC issue in other
ways.
