Description of problem:

There is an encoding issue with german special characters like 'ä' when using task form. Performing some tests using task form and business-central, I realized that it stores an invalid character (i.e. ��) in database and Instance Data (business-central).

select * from variableinstancelog;
  id  |        log_date         |          processid          | processinstanceid | value  |     variableid      | variableinstanceid

It seems that there is something broken in the BRMS platform when doing human task form processing regarding the right encoding/decoding. Also, this is not a database issue since it stores the right character when adding it directly in the table. Other point, it is not being experienced when using "Script Task", only by using task form.


Steps to Reproduce:
1.) import the repository_export attached to guvnor
2.) Start the process with the business-central
3.) A form with one textinputfield should appear
4.) Enter something like 'äää' and submit
5.) Have a look in the business-central -> Processoverview -> EncodingTest -> instance -> instanceData
6.) Output will show broken char in variable 'testProcessVariable'
7.) Check value stored in database (table: variableinstancelog)

Actual results:
Broken char in variable and database.


Expected results:
Right char.
