Fix bug causing messages containing newline byte to disappear

Browse Source 
The wcswidth() function was silently failing when trying to convert
messages containing a newline to a widechar buffer which resulted
in the message showing up as an empty line. we now fall back
to using strlen to get the width of the string, which might still
cause minor display bugs when the message contains unicode, but is
still better than losing messages entirely.
