if anyone can tell me if you can type the nonstandard characters into constructs textboxes, itd be a start
I don't know if it's possible. The usual Windows way - which at least works okay in WordPad, if not Notepad, or a web browser - doesn't seem to work in Construct.
You can copy and paste them, or some of them, it seems.
The tool gives output such as: � 224, � 225, � 226, � 227, � 228, � 229, � 230, � 231
That tells you you need to hold alt, then press 0224 on the number pad, to get �. Doesn't work in construct, but it works in Wordpad. It looks like that line can be copy and pasted, though - and those even show up with the Text object.
Here is the tool: http://dl.getdropbox.com/u/1712024/chartool.html
One thing the "HTML evaluator" setting in it is useful for is entering HTML like à, the kind of things the "Character Value (HTML)" setting outputs.
"almost all unicode.html" is the file containing those Unicode characters. It might take a short time to load/display, since it is a long file, and will make your browser load whatever fonts those characters are in.
Feel free to pass those around, use them for anything really.
