SNMP Community Strings

Are there any limitations on community strings that can be used in Solarwinds? I'm asking because I am going to be updating these on several devices and they're going to be a mix of upper/lower, numbers, special characters and 25+ characters or longer in length. I'll do some research on the device limitations, just curious from a Solarwinds standpoint. I've tried searching for an answer but came up short. If someone can direct me a document with character limitations if any it would be appreciated.
