* Streaming into an FTextView() object
* Fixes the streaming of empty FString objects into a stream with
a width > 0
* The FString operator [] now returns a null character ('\0')
if the position is equal to the string length
2019-09-28 Markus Gans <guru.mail@muenster.de> 2019-09-28 Markus Gans <guru.mail@muenster.de>
* Support for displaying full-width characters (2 columns wide) * Support for displaying full-width characters (2 columns wide)
