Mail encoding error

[rodrigorapozo]

After to change somethings in "Data Dictionary/Email Templates/activities/activities-email.ftl" my mail notifications stopped with this erro in log.

Failed message 1: javax.mail.MessagingException: Unknown encoding: ${mail.header}‍

Notes: If I try change the html on terminal with vim the charset/encoding don't change, but if I change on browser the charset/encoding change from utf8 to ascii I tried to use vim, iconv and recode but the only way to change the charset/encoding was putting accented character in file.

Thanks a lot

What changes have you made to the activities template?   Have you added any non ascii characters?   If so how?

Just change one image in template, but because I made this change with the browser the file was saved with another encoding (utf8 to ascii) I don't know why. The only way that I can put the file again with utf8 was putting one non-ascii like "á" in file.

Thanks for the help
