UnicodeDecodeError: ascii codec can't decode byte 0xc3 in position 47: ordinal not in range 128

[ntmlod]

Dear all,

I've just created my first form page thanks to the TracForms plugin:

{{{
#!TracForm
#!subcontext abstract
#!submit_label 'Submit Abstract'
#!keep_history yes
...
}}}

Everything works well until I want to see on my first copy how the history recording renders by clicking on 'Form details' link.

While doing a GET operation on  /form/3 , Trac issued an internal error.    please provide additional details here    Request parameters: {{{ { id : u 3 } }}} 

You can find all the informations about our own installation and how to reproduce the bug.

TracForms 0.5dev: Fix markup generation

Refs #12681.

[Ryan J Ollos]

Please upgrade your Trac instance to 1.0.13 or later. If you still see the problem with the latest TracForms, then I need to see the exact markup to reproduce.

[Ryan J Ollos]

See #13127 for Trac 1.2 support.
