Sorry, I'm clueless about Unicode; noting leaps out of the docs to
If there isn't a clever Unicode method, you could do the following ....
note it ignores the more complex parts of UTF-*, and deals only with
those chars that can be represented in 2 hex digits ....
It uses replace to do the actual changes - but only does one replace for
each character encoded in the original, so should be pretty fast (NB :
not tested for speed - only for working correctly in simple cases).
local tText, tArr, tNew, tmp
put the text of field "inField" into tText
put tText into tmp
split tmp by "&" and ";"
put the keys of tmp into tArr
filter tArr with "#x*"
repeat for each line L in tArr
put baseconvert(char 3 to 4 of L, 16, 10) into tNew
replace (char 2 to 4 of L) with tNew in tText
put tText after msg
