[chirp_users] Comment field limits?

Programming a Baofeng BFF8-HP:

I noticed when the Comments field is populated, I am unable to use a properly programmed repeater. When I clear all the comments from the field, reset the radio to factory settings, then reprogram with CSV (cleared of comments), the repeater function is as expected. Reprogramming via CHIRP without resetting the radio to factory settings does NOT clear the problem.

Is there a limit to the number of characters the comments field can hold or are there certain characters (comma, open/close parens, underscore, dash, slash, question mark, decimal/period, space, equal sign, digits?) one shouldn't enter there?
