Status: VERIFIED FIXED

(Core :: DOM: Core & HTML, defect)

Description

See http://www.w3.org/Bugs/Public/show_bug.cgi?id=12915.

We basically need to include the Arabic and Persian digit ranges in the regular expression that we use to see if we should accept those characters, and also make sure that we can parse them for the purpose of internal storage (and form submission).

Mounir, can you please point me to where that regex lives?

There is no code doing that for the moment (if you speak of <input type='number'>).

So, how does <input type=number> work right now?

It's not in the tree... and the WIP implementation I have doesn't handle that but it doesn't handle a lot of other stuff too.

I think we should include as "digits" any codepoints with the Unicode General Category of Decimal_Number (Nd). For the record, there are currently 42 x 10 of these, listed in the last section of http://unicode.org/Public/UNIDATA/extracted/DerivedNumericType.txt.

I'm planning on using icu::DecimalFormater for this, but it seems that isn't possible from libxul just yet. I'll need bug 915735 to be fixed first, and that may take some time.
