Description Raúl 2015-07-29 21:49:58 UTC

I have an email source in a text file. I use kmail --view <file name w/absolute path> to open it in a composer.
Even "Content-Type" header specifies UTF-8 charset, kmail composer is unable to cope with encoding, showing ugly characters instead of the right ones.

Reproducible: Always

Steps to Reproduce:
1. Download attached sample-email file
2. kmail --view $(pwd)/sample-email


Actual Results:  
Non-ascii characters, like 'á' are not shown properly

Expected Results:  
Non-ascii characters, like 'á' are shown properly

Interestingly enough, I have the following results using "kmail --view" with these attached files:
- Sample email with iso-8859-1 text body (Content-Type UTF-8): Shown correctly, even Content-Type is wrongly specified as charset=UTF-8
- Sample email with iso-8859-1 text body (No Content-Type specified): Shown incorrectly.

I have tested Kmail preferences -> composer -> charset with default "us-ascii" as first option and prioritizing utf-8 (either as system locale or forced) with no differences in behaviour. 

Also when opening email file, I have tested changing encoding in view->set encoding. Default is auto, but trying utf-8 works for any of the iso-8859-1 encoded files. For utf-8 email, choosing utf-8 encoding in the view menu does not work and any other worsen things.

Doing kmail --view would be a typical use case when I want to send a git format-patch generated file.

I have experience this wrong behaviour since a long time ago. Only that I hadn't reported it. Also, I used to convert files to iso-8859-1 to sort out the issue.

I have the same problem, and found a workaround for it:
