I am not sure if I could glean this from the current LC docs but it doesn't

I have a desktop app which contains a field into which the user can type a
character string which is then manipulated by the app. The user can just use
the keyboard, but they can also paste something into the field. This may be
a) straight ascii
b) the extended Mac character set with things like the symbol for pi (I'm not
typing that here because it may not be readable at your end)
c) whatever is allowed in 'normal' PC apps like Microsoft Word
Wow: how I dislike the fact that 'PC' = 'PC running Windows'.
c) full Unicode, derived from some display on a web site or elsewhere which
simply operates in Unicode.
I am prepared to do my manipulation entirely in Unicode, since in a way this is
a superset of anything else I might have to handle (OK not quite, because the
Mac has its own non-Unicode extended character set) - but my problem is, how am
I to know what the text in the field consists of? Naively I think that some of
the 'characters' will be single byte and some double, which makes everything
look extremely uninterpretable, but maybe not.
Can anyone suggest how to proceed with handling input like this? Can I just
flag the input field as Unicode and relax? Probably not.
TIA

I have a feeling that, in your script that is either typed in or pasted
into, before either
the typing takes place or the pasting you must do a:
set the useUnicode to true
something like this, maybe, in the card script:
on keyDown
set the useUnicode to true
end rawKeyDown
wow; I just wrote a pile of stinking sh*t as that blocks the letter
input; similar probs with rawKeyDown.
ASCII is a subset of Unicode.

Why do you need "to know what the text in the field consists of" ?
Surely you only to know that if you are going to do "things" with the
text after chummy has typed/pasted/whatever the text?
I (on Linux) have just typed some 'goobledygook' using the Nepali
keyboard layout (looks suspiciously like Hindi Devanagari, and prob.
the only difference is some hairy-chested sort of Nepali nationalism),
and it entered the textField "just like that".
went here: http://www.doe.gov.np/ Lovely website; cannot understand a
single thing; but marvellous for trying copy-paste into
Livecode fields.
Copied and pasted a random paragraph; and it pasted looking exactly as
per the website.
So, certainly from the point of view of text-entry and/or pasting you
can 'relax'.
---------------------------------------------------
"flag the field as Unicode" ?
I wish I knew how to do that!
---------------------------------------------------
"relax" Ha, Ha, not a chance chum.
---------------------------------------------
I have just had one of those lovely day-dreams where I really Grokked on
this idea:
if fld "fTEXT" contains unicodeText then
put "Wow-zah"
end if
anyway . . .
apart from getting Tom Wolfe stuck between my teeth . . .
Nothing was PUT either with the pasted Nepali text, or when I had put a
unicode char into the fld like this:
set the useUnicode to true
set the unicodeText of fld "fTEXT" to numToChar(7891)
So . . . I'm not being much help really.
Richmond.
