mail Mime Parser Error - and adding vendors like guzzle composer library

[alexmiller]

I am getting a SQL State Error caused by the copy right symbol
the error in the log is
[2018-08-07 15:24:07] Espo.ERROR: InboundEmail 5b26f7ecbbf65bca0 (Import Message w/ MailMimeParser): [HY000] SQLSTATE[HY000]: General error: 1366 Incorrect string value: '\xA9 2018...' for column 'body_plain' at row 1 [] []

i know this is a thrid party library but i cant seem to figure out exactly how to encode the body_plain??

also how can i add vendor to the vendo library using composer... for example try to add the guzzle API library using composer will break the entire install on any version?@?

could you check the charset and the collation of this field / table / database?

[alexmiller]

the body_plain collation is:

utf8mb4_unicode_ci
