Hi,
for our turbine-based application we started use intake for form fields
validation. Our customers use non-Latin charsets for data entered into
form fields, but we were unable to validate them using intake.
Intake currently uses ORO for regexp validation, but ORO doesn't handle
the unicode perl5 regexps (like \\p{L} for Letters in any encoding, not
only A-Za-z).
The sun's java.util.regexp. package these unicode regexps implement, so
I decided to rewrite the StringValidator in intake to use
java.util.regexp classes instead of ORO. The patch against turbine-2.3.2
is attached bellow. We test this patch internally, but for now it seems
to work OK. This way turbine is able to handle unicode inputs checked by
intake.
If someone has some complains about choosing sun's java.util.regexp for
this patch, drop me a note. The only downside of choosing
java.util.regexp is the dependency on JDK1.4 or higher.
