Inserting a character (LC 7.0.1)

[Graham Samuel]

Thanks again - it's all a bit too clever for its own good, IMHO. A nice convention like "the insertionPoint" would be easier. Still, nobody is going to change the language just for me...

I am now struggling with doing this insertion business in Unicode. Turns out you can't just paste a Unicode character into a LiveCode script on a PC if say you want to test against it, as in

if myChar = "$"

where instead of $ you want some Unicode character copied from a web page or something like that. You may even see the character on the screen, but when you close LiveCode and reopen the stack in new activation of LC, that glyph is replaced by "?". It seems you have to use numToCodePoint and its inverse. But I am still exploring...
