Bug#1049522: double build failures in libvitacilina-perl

[Étienne Mollier]

On both #1046029 and #1049522, the error shows:
> Error reading from file 'META.yml': UTF-8 "\xA1" does not map to Unicode
>  at /usr/share/perl5/Module/Install/Admin/Metadata.pm line 14.
> make[1]: *** [Makefile:832: realclean] Error 25

This is caused by the YAML parser to choke on the inverted
exclamation mark in the abstract which should be valid UTF-8[1]:

	$ echo -e '\xC2\xA1'
	¡

It looks like something in the parsing does not capture the C2A1
properly, and jumps straight to the A1, not sure what yet.  It
could be an issue in YAML::Tiny, or in perl (although I would
have expected much more fallouts if the latter).

I will move on to lower hanging fruits for now,  ;)
