Bug#825932: freeorion: Segfault on entry of dead_macron

[Thanasis Kinias]

Package: freeorion
Version: 0.4.5+git20160501-1
Severity: normal
Tags: l10n

Dear Maintainer,

I’m seeing an odd crash resulting from typing a dead_macron (i.e.,
typing a macron deadkey).

What I’m doing:  Try to rename a fleet after the star system ‘Fehū’.

What happens:  As soon as I hit the macron deadkey, attempting to type
the ‘ū’, FreeOrion segfaults.  The following appears on the console:

> terminate called after throwing an instance of 'utf8::invalid_utf8'
>   what():  Invalid UTF-8
> Aborted

I can reproduce this in a minimal case where I start up FreeOrion,
quick-start a new game, and do a rename as the very first action.

I did a strace -f of this minimal case, but the result is still 82 MB, so
I’m not attaching it here.
