Description:	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 now reproduce the issue : 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: {noformat} ERROR[30993][C-00000024] json.c: Error building JSON from '{s: s, s: s}': Invalid UTF-8 string {noformat} The accent characters will be missing from the $\{VM_CIDNAME} variable and the sender's name will be incorrect in the email. Check my  log, The callerid name was Émile François.

The value of {{ç}} in your file is a single byte with the value {{0xE7}} which is invalid UTF-8. My guess it that whatever device you are setting this Caller ID with is using the Windows 1252 code page instead of UTF-8.  You should overwrite it by copy/pasting the following, valid UTF-8, verbatim into your user agent and trying again: {{Émile François}} If you confirm that your user agent (or whatever is supplying your Caller ID name) is correctly configured and feel this issue was closed in error, please feel free to re-open.
