Description

After merging a commit in one of our repositories, I saw this in the log, which says it was unable to deliver the notification.

P=C3=A9ter

Should be

Péter

which is used as the Full name for that user (acquired through Active Directory), so I think the latin/utf8 character

é

causes the mentioned error.

Seems to be validation problem as UTF-8 email address is correct

I'll check tomorrow if this happens all the time, since I do remember receiving some notifications. Is the error message for not being able to deliver mails because e.g. the mail server is not available the same, or different?

[lafriks]

I could be wrong but seems to be validation in Gitea code

[rems4e]

I'm facing this problem right now, where all of the people in my team have a name with characters out of basic latin character set… So none of them are receiving the emails :)

By the way the emails are generated by tickets update, if that's relevant.

Gitea is in version 1.1.4.

Hi rems4e,

Our workaround for the problem was to replace/remove these characters in the Gitea database (since the full name was coming from AD we could not edit it on the UI) and since then everyone is receiving emails.

Hi,

Thanks for the hint. But this is not really acceptable for us, as the directory is used for other stuffs that can't accomodate with this change.

Anyway, this is a bug in Gitea that is a little cumbersome at the moment :) Maybe I could have a look and try fixing it?

[lafriks]

@rems4e you are more than welcome to try to fix it and send PR

[rems4e]

@lafriks OK, that should be feasible. However, could you please hint me where to start? Mainly, on which branch should I base my work? I've had a look at the contributing info but I'm not sure it answers all of my questions :)
