Error in encoding UTF-8 and ASCII-8BIT

[MauricioAlgalan]

My vmail don't open some e-mails because have a error in encoding: "Error in encoding UTF-8 and ASCII-8BIT".

I tray some older solutions but do not work. I have gems 2.5.0 and vmail 2.9.11.

I work with emails encoded in non English languages and I do not see this issue at my end. Since you have ruby 2.5.0 installed, it should be able to handle any encoding.

If I could have access to one of the affected emails, it would help me replicate the issue on my end. If possible, please attach one of the affected emails to this ticket.

Thanks for any suggestion on how to solve it.

Reverted to version 2.9.10 issue is no more present... something failed in 2.9.11 :-)
