            Severity: Minor
         Attachments: debug_log_JSON_Accent, voicemail.conf

I had this error in my console since at least Asterisk 13.5.
I did ask on the forum at the time but I could not reproduce the issue:
https://community.asterisk.org/t/random-error-utf-8-string/49703/4

I can reproduce the issue as I want:

If a caller leaves  a voicemail and the caller's ID name contains accent characters and the message is sent by email, it will produce the following error:

ERROR[30993][C-00000024] json.c: Error building JSON from '{s: s, s: s}': Invalid UTF-8 string

The accent characters will be missing from the ${VM_CIDNAME} variable and the sender's name will be incorrect in the email.

Check my full DEBUG log, The callerid name was Émile François.
