Description
When I type HTML special chars on a TeaxArea, my application crashes.
While monitoring the 'change' event, I noticed that Titanium is trying to replace (at least in the logs) the HTML entities for characters, which may be causing the error.
Here is the stack trace including my textarea logs:
[DEBUG] text is: & [DEBUG] text is: &l [DEBUG] text is: < [DEBUG] text is: < [DEBUG] text is: < [ERROR] The application has crashed with an

Added logs as an attachment as well.
The bug stopped happening after removing the replace on 'shouldChangeTextInRange' (TiUITextArea.m, line 136).
Was:
NSString *curText = [[tv text] stringByReplacingCharactersInRange:range withString:text];
Changed to:
NSString *curText = text;
I have been able to reproduce this bug, but it only seems to happen when you also have invalid and valid HTML entities in your text area already.
