xoxco tagging : force lowercase to avoid duplicates

Question

Trying my hand on the xoxco tagging plugin.
It works great, however, it doesn't identify that the same words in different cases are duplicates, e.g. :
"This" and "this" is considered the same.

There is no hook before the tag actually gets added, where one can capture and modify the input.

Is there a way to add a hook or convert it to lower ?
