Depending on the tagged charset, various things will go wrong.

If the charset tag is 'UTF-8' it's useless info, so the printer
will guess the script and character repertoire and _font_ based 
on the language tag - which fall back in this example to 'en-US'.  

That font won't contain the accents necessary to render ga-Latg-IE,
so a bunch of those annoying little black squares will replace every
character that's not in the US-ASCII subset of the Latin script.

Which seems serious to me, but perhaps it's just that user's
problem, huh?

Cheers,
