Thanks for the response Devin, but I'm still unclear how you DO

with the data stored in the variable item offsets, line offsets,
comparisons, etc). A kind listmember clued me into the fact that
you must
first uniEncode the thing you want to find in the variable, and I
have since
found that by uniDecoding the variable I can get at my English/Roman
content.
I'll confess, that most of my work in unicode has involved displaying
rather than analyzing or manipulating the text in any complex way. I
worked on a way to sort Cyrillic unicode, but it was a killer, and I
never got it exactly right. I think in general you're going to have a
hard time doing some of this stuff in variables, since there is no
unicodeText property of variables, only the raw strings of bytes. I
tend to put everything in a field, even if it's hidden, and do stuff
that way. Statements like
line 2 of the unicodeText of fld "foo"
word 3 to 5 of the unicodeText of fld "bar"
seem to work just fine. Given that, if I were searching for strings in
unicode text, I'd probably do it something like:
put the unicodeText of fld "searchterm" into tSrchStr
put lineOffset(tSrchStr,the unicodeText of fld "searchcontainer") into
tLineNum
You could also try doing everything with UTF-8:
put unidecode(the unicodeText of fld "searchTerm","UTF8" into tSrchStr
put unidecode(the unicodeText of fld "searchcontainer","UTF8") into
tSrchCont
put lineOffset(tSrchStr,tSrchCont) into tLineNum
This is all untested. Just my hunch given what I've learned about how
unicode works in Rev. If you need to, say, select said found unicode
text in a field, it could get dicey.
But it seems that doing all the standard variable manipulation
we're used to is much more complex/fragile when dealing with Unicode.
That's pretty much the takeaway message. Everything is doable, but
more fragile and complex. That said, once you figure it out, it's
pretty stable and reliable.
In any event, thanks for the pointers to the stacks. I found several
example stacks around the 'net (including your site), and though
each seems
to have some examples that don't work properly, the majority of info
is
helpful.
If you found any of my examples that didn't work, I'd love to know, if
you get a chance to pass them on.
