[Zope3-dev] Bytes versus ASCII
Hi, (this is about zope.schema) I assumed that the fields Bytes and ASCII have some distinction. The ASCII field explicitly checks for every character to have an ordinal value lower than 127. Bytes however does a cast in fromUnicode(u) that does str(u). This will break if there are non-ascii characters in the unicode string. Effectively this makes it an ASCII field as well. However, I don't know enough about the environment, so eventually this is all good. When does the fromUnicode method get called? Everytime I use this field through zope.app.form or zope.formlib?
