Normally something like that would be done in the Validate method, but 
that is not called for every character, only when the dialog is 
completed.  You don't want to do it in the EVT_CHAR handler since the 
new char has not been inserted into textctrl yet.  But you could use 
wx.CallAfter from there to cause a method to be called after the 
character has been inserted, and from there you can get the value of the 
control and check it however you like.
