Regards Peter I installed the Unicode consortium's Last Resort font: http://www.unicode.org/policies/lastresortfont_eula.html and ran the script: on mouseUp set the useUnicode to true set the unicodeText of fld fff to (numtoChar(55357) numToChar(56832)) end mouseUp and got a char saying undefined 1 1FFFD Plane 1 U+1FFFD = 131069 U+1 = 65536 so, that, at least, makes sense; and that would argue that a font with the smiley face should show the face. AND; according to this: http://www.fontspace.com/unicode/char/1F601-grinning-face-with-smiling-eyes we should be OK: so, adjusted the second surrogate pair to U+1F601 = 55357 56833, used DejaVu Sans, and got a smiley face !! Obviously, DejaVu Sans does NOT have a glyph at 1F600. then, did this: on mouseUp set the useUnicode to true put the unicodeText of fld fff into FFF put charToNum(FFF) into fld NUMM end mouseUp and the number I got was 55357: the first number in the surrogate pair! So it would seem that the surrogate pairs work in one direction [ numToChar ] but not the other way round [ charToNum ].

Hi Richmond, My bad, should have been: numtoChar(55357) numToChar(56832) Note that current versions of LiveCode don't really treat surrogate pairs properly - each codeunit of the pair is treated as a character so it is possible to do things like apply a style that only affects one of the two units.

Re: numToChar with socking great numbers
Hi Phil, We do intend to have RTL support in the 7.x cycle. What is most likely to happen is that we'll initially introduce a simplified mode where a field is exclusively right-to-left or left-to-right and mixing isn't really supported. (Individual words in a mixed setting should render in the right order but e.g. English text in a Hebrew field will this like render) Full bidirectional support is the eventual goal but may take some time to implement and test properly as it requires extensive changes to the way fields currently lay-out and render their contents. Once this happens, RTL and LTR text can be mixed freely in a field and it should just do the right thing. By right thing, I mean that it will detect when a section of RTL or LTR text is embedded in an LTR or RTL field and ensure words are placed in the correct order. The Unicode RTL control characters will be obeyed for overriding the defaults where necessary. The really fun part to get right is cursor positioning in mixed-direction fields; imagine you have an LTR field with: latin arabic | where | is the cursor position - if you type in some more arabic text, it should actually be inserted immediately after the latin (to the left of the existing arabic) rather than at the cursor position on the right. And how should the cursor move as you navigate the field with the arrow keys? So the short answer is yes, but… ;) Basic RTL functionality should happen in 7.0 or 7.x; full BiDi support is complex enough that it will take longer and I can't say for certain when it will appear.

Re: numToChar with socking great numbers
That’s really exciting news; it’s long overdue but still exciting.
But I don’t think the users {we, programmers} will complain much about
bidirectional support.
Even the biggest services don’t give full support to bidirectional text.
I remember that I once published a short fairy-tale of mine to Facebook.
The title was in Hebrew {RTL} - just to be exotic :) - and the story was in
Turkish {LTR}.
Facebook totally messed it up with the punctuations.
The story seemed like this:
.Lorem ipsum dolor
,sit amet ad holorem
;ti malus prefericarus
Changing back the title to Turkish didn’t help either;
since I didn’t want to lose all the comments and likes, I left it as it was.
So, bidirectional support is truly a complex job.
Give us a dedicated RTL field, we’ll be happy enough;
I’ll be happy enough, for one :)
Best,
~ Ender Nafi

I thought I'd have a go at surrogate pairs: http://www.russellcottrell.com/greek/utilities/SurrogatePairCalculator.htm and was told that 1F600 was equal to D83D + DE00 : a.k.a. 128512 = 55357+56832 so did this: set the useUnicode to true set the unicodeText of fld feeld to numToChar(55357+56832 no joy.

Re: numToChar with socking great numbers
You need two numToChar calls: numToChar(55357)+ numToChar(56832) The Unicode engine will fix this with a new call that handles surrogate pairs automatically and invisibly but numToChar will probably have to retain the mod-65536 behaviour for compatibility.

Regards, Fraser Thank you very much for that. So, Livecode does work with surrogate pairs; just that I didn't know the syntax, and couldn't find any reference to it in the documentation.
