iOS keyboard character import infinite loop

[mathieugarcia]

On iOS, while inputting text from the system keyboard, some characters will make nglString::Import run into an infinite loop, while converting characters (UTF8 I guess).

The bug can be triggered by following these steps:

• Bring the iOS keyboard
• Press the ".?123" button to bring special characters
• Hold and press the "-" button
• Select the second dash character

nglString::Import(int32&, const char*, int32, nglStringConv&) will loop forever in the do/while statement.
(to_read = 2, to_write = 2, rOffset = 0)

Tested on iPad - iOS 5.0 and 5.1
