Characters and chartab

[Zachary Kline]

Hi,
	I was curious as to the purposes of
	/sys/modules/speakup/parameters/chartab and
	/sys/modules/speakup/parameters/characters.  They both seem to
	contain character tables of some kind.  I was wondering how
	they're populated, and what charset if any they're configured
	for by default?  I've noticed some symbols being pronounced,
	such as Greek letters, and was wondering where they come from.
Any information on this would be appreciated.
Thanks,
Zack.
