Bug 681632

Description of problem:

This is a bit of a nitpick.
If one tries to edit a user password and enter multibyte characters, s/he cannot.  However, they can be pasted into the box.  (Likewise, on the login screen, user cannot enter them but they can be pasted in)

Version-Release number of selected component (if applicable):


How reproducible:


Steps to Reproduce:
1.  Administration > Users > $user
2.  In the Password field, using an IME, attempt to enter the characters "一二三一二三"  note that you probably cannot enter these -- you see a dot entered for each character you've typed, instead.
3.  Attempt to paste in the same string to password/verify password fields.
4.  Attempt to login as said user, using the methods listed in steps 2 and 3 above.
  
Actual results:
User cannot use IME to enter multibyte chars into password fields.  They can, however, paste said characters

Expected results:
I'm really not sure we necessarily want/need to allow them to enter such characters - but if we decide to block it, we should parse password strings prior to submittal to disallow such characters as well.

Additional info:

This very well could be a limitation of the toolkit, browser, or even the IME on the system (Fedora in this case).  And I am fine with disallowing multibyte characters as passwords.  But if we do so, we should make sure they cannot be entered in myriad other ways.
