Maybe unnecessary for LC7, but for my work in LC6 (and anybody that's
interested), I put together the following functions for converting a
unicode surrogate pair to a single value and vice versa:
function unicodePairToNum pNum1,pNum2
return (pNum1 - 55296) * 1024 + (pNum2 - 56320) + 65536
end unicodePairToNum
function numToUnicodePair pNum
put trunc((pNum - 65536)/1024 + 55296) into num1
put (pNum - 65536) mod 1024 + 56320 into num2
return num1,num2
end numToUnicodePair
Thanks to Richmond for the link to unicode character calculations:

Love, Richmond.
One item that would be helpful to know is at what value does a unicode
character start being represented as pairs? Is 65536 the upper limit for
single value characters?

Hi All:
I thought I had figured out the display of Unicode glyphs in LC 6.6, and
then ran up against a threshold where the value of a character is
displayed as two values. I'm guessing this is related to a "double-byte"
something or other. How does one retrieve the value of a character as a
single value?
For example, I can set the htmlText of a field to 📞 and get the
correct unicode character to display. But when retrieving the value for
the character, I get: ��
Can I encode/decode/jumpcode/flipcode something here to get a single
value
representation of the character?
(Also, I'm unable set the value of the by setting the unicodeText to
numToChar(128222) -- only using the htmlText property seems to work).
Thanks for helping out this uniclueless dude.
