Tamper fails when comma is in Text to replace

Greetings,

I have Find and replace plug ins where the "Text to replace" value has a comma, e.g. "Charleston, Oakland, and the Mid-Atlantic."

The "Text to replace" value is equal to a Taxonomy term.

I find that the data is not imported when the "Text to replace" value includes comma punctuation.

Other than removing the commas from the term, or massaging the source data, can anyone suggest a work-around to this problem?

Thanks - Mike
