Syntax error in mailbox address when using Send SMTP Mail Message (non-printable character)


I use Send SMTP Mail Message activity and whenever it tries to send an email that has non-Latin characters (é, á, Æ, etc.) - it fails.

I receive the following error:

Syntax error in mailbox address "ex?" (non-printable character) Source: Send to customer: Send SMTP Mail Message

For emails with regular Latin characters, it works fine.

Studio version 2019.4
Mail.Activities version 1.4

Are there any ideas on how to fix this?

Thank you

write that user name in a text file with WRITE TEXT FILE ACTIVITY where in the property panel mention as “UTF-8” along ENCODING property
–again use READ TEXT FILE ACTIVITY and get the output with a variable of type string
with same encoding property mentioned
–now pass that variable as input to username in SEND SMTP MAIL activity and try once
