Description deloptes 2016-09-09 10:52:21 CDT

The problem I have is (again related to UTF-8 items) but this time in calendar/todo (libkcal).
This bug is to track the work on this issue.

I finally was able to find a way to reproduce the problem. Here is the procedure:

1. Create an item in UTF-8 (I use Cyrillic and German) in kontact/kcal
2. Sync the item to the phone
3. Modify the item on the phone
4. Sync the item to TDE

At step 4. most of the UTF-8 text gets some non ascii chars replaced with =\n
which breaks the calendar and causes a massive mess.

I have seen somewhere a basic utf check, which probably does not work properly.

I just found out that knotes is using the journal resource and writing to ical format, which may explain why I'm observing similar issues in seemingly unrelated knotes application.
Why would one  write a dcop interface for libkcal journal :| ?!

I traced this down to vcal, but not sure if it is coming from vcalformat or something else.

Here is an example

The problem seems to be blank in the beginning of the following line. This breaks the quoted printable conversion in vcal.
An easy solution would be to strip blank from start of the line if this is quoted printable (or perhaps also other format), but I don't know how to do this with the yacc vcc.y file properly.

I tested this with

libkcal/tests$ ./testvcalexport test1.vcs testout.vcs
