appsmith: [Bug]-[232]:Encoding issue with SMTP plugin

Is there an existing issue for this?

• I have searched the existing issues

Description

From community:

i would like to ask a question about the SMTP app. We are currently successfully sending mails with it, however there is a strange thing happening with umlauts. The header of the sent mail says:

Content-Type: text/html; charset=UTF-8
Content-Transfer-Encoding: quoted-printable
 
but the generated source code of the email clearly has ISO-8859-1 encoding:

bittet um R=FCckruf

the correct utf-8 quoted printable would look like such:

bittet um R=C3=BCckruf

are we missing something here, or should this be considered to be a bug?

are you seeing any issue with the email that is received at the other end ?

yes, Mail.app under latest macOS is not able to display the text correctly.
we tried to supply an html skeleton in which we supplied the ISO-8859-1 encoding as a charset directive, but that gained no success either.
