The text is truncated, not simply not displayed:
on mouseUp
put "1234567890 " into temp
repeat 10000
put temp after accum
end repeat
put accum into fld 1 -- 110,000 chars
answer the length of fld 1
end mouseUp
You get 65,533.
Not sure where the last two chars went.

Reading a file always gives you all the content regardless of the size, up to
memory limits. Displaying a long line of text will truncate it after 62k but as
I understand it, the truncation is visual only. If a script asks for the line
it is all returned. (Better check that, but that was my understanding.)
But the restriction only applies to lines that don't wrap, such as those in
list
fields. If the text contains spaces or other delimiting tokens, the text will
wrap and the restriction is lifted.
When reading a file from disk as text, line endings will be converted to the
ones used by the current OS. Text read as binary will not be altered.
