[PATCH] t7400: test of UTF-8 submodule names pass under Mac OS

["Torsten Bögershausen" <tboegi@web.de>]

submodules with names using UTF-8 need core.precomposeunicode true
under Mac OS X, set it in the TC.

Improve the portability:
Not all shells on all OS may understand literal UTF-8 strings.
Use a help variable filled by printf, as we do it in e.g. t0050.

"strange names" can be called UTF-8, rephrase the heading
