Hi Massimo,
Here's a simple test example:
Controller:
def utfinput():
s = u'\u2026'
form = FORM('Test',
INPUT(_name='test1', value=s),
INPUT(_name='doit',
_type='submit', _value='Submit'))
if form.accepts(request.vars, session):
session.flash = "Accepted"
return dict(form=form)
View:
{{ extend 'layout.html' }}
{{= form }}
Resulting html:
<form method="post" enctype="multipart/form-data" action="#">Test<input
type="text" value="…" name="test1"><input type="submit" value="Submit"
name="doit"><div style="display:none;"><input type="hidden"
value="5de6bf73-616e-45b8-95e2-751ac1f64716" name="_formkey"><input
type="hidden" value="default" name="_formname"></div></form>
If I use the _value parameter instead of the value parameter for test1 (as
I have been doing) then it throws
an error ticket because the handling of the _value parameter is not unicode
safe.
The distinction between value and _value is not entirely clear to me and I
suggest
that the first example in the INPUT section of the book should perhaps use
value instead of _value.
In any case, I reckon it should be acceptable to use unicode with _value.
