[Qemu-devel] [PATCH 1/2] Support @documentencoding in scripts/texi2pod.pl

[Michael Tokarev]

Currently our texi2pod ignores @documentencoding even if it is set
properly in *.texi files.  This results in a mojibake in documents
generated from qemu.pod (which is generated from qemu-doc.texi by
texi2pod), because the rest of the tools assumes ASCII encoding.

This patch recognizes first @documentencoding in input and places
it at the beginning of output as =encoding directive.
