Encoding ’ apostrophe server error 500

Post by Sayannara »

If an email include ’ which is the character for the apostrophe (encoded in :twisted: MS product like Outlook, Word, ..) when I reply or create a ticket, I get an Server error 500. The email is not sent but it appears in OTRS...

I added in my Config.pm

Code: Select all

$Self->{DefaultCharset} = 'utf-8';

Was fine within Windows, please what can I do with my Linux installation ?

Re: Encoding &rsquo; apostrophe server error 500

Post by Sayannara »

I know OTRS in really more for the "Linux World" but I am sure a lot of people use Outlook to write email and thus open ticket within OTRS. I can't imagine that I'm the only one to have this issue.

this is a summary of following links:
It seems that there is a problem with the version of libmime-tools-perl with OTRS 3.1.x. I'll try to upgrade to 3.2.x->3.3.x and see if it is better.

keywords: MIME

Code: Select all

That's definitely what I would recommend for you. I highly recommend checking your system after each upgrade and go straight to OTRS 4 or OTRS 5.
But this will depend on the addons you use.

Use a test system - always.

Do you want to contribute or want to know where it goes ?

Ok I upgrade to 3.2.18 and the problem is solved.

Yes I planned to upgrade to version 5. But... As a Windows sysadmin it takes time! The documentation is poor I think especially for someone who doesn't know Linux, perl, db, ...
Well with your help I will :D
