The solution to having line breaks work when using UTF16 text is to not do
that, it doesn't work.
I tried several characters that contain a byte that could look like a return
and ... when the text is UTF16 that byte of a normally legit unicode character,
is treated as a return. My favorite test character was 0A0A which looks like a
guy with a baseball cap sticking his tongue out and two wiggle lines underneath
to indicate motion.
Anyway, the solution that seems to work is to keep the data in UTF8 and then
split it into an array where each line goes into a separate array element.
Then instead of line 5 I look at lineArray[5]
Sure wish LiveCode dealt with unicode as a first class citizen.
