We should localize it on the browser (trusted) side if possible.

I don't think we can do that.

We want to show the same localized value in the dialog and in the web page.
We have written a LDML parser inside Blink to do the localization properly and
it would be hard to bring it over to the browser process.

Does the browser side check this for sanity in some way? (Probably: contains
only printable characters, is shorter than some reasonable max length.)

[keishi, 2013/11/06 04:28:46]

We don't do anything right now.

In my next patch I'll trim the length down to 256 characters in the browser and
renderer.

How do I check for printable characters? "label" will contain non ascii
characters.
