Unicode to RTF problem

General
#1

I’m using Cocoa, if that matters:

Can Xojo handle negative unicode codepoints? I have a Japanese user who reported that using this character

? – CJK UNIFIED IDEOGRAPH-98DF according to the Character Viewer

was causing problems. I am storing the text as RTF, and when I look at the StyledText.rtfData for a textArea with this character I get an empty value:

{\rtf1\ansi\ansicpg1252{\fonttbl{\f0\fnil HiraKakuProN-W3;}}{\colortbl\red0\green0\blue0;}\uc0 \f0\fs24 }

If I try to assign the correct RTF unicode entity, \u-26401 to RTFData, like this

textArea.styledText.RTFData = “{\rtf1\ansi\ansicpg1252{\fonttbl{\f0\fnil HiraKakuProN-W3;}}{\colortbl\red0\green0\blue0;}\fs24\f0 \u-26401?}”

the result is the same, no text.

I’ll file a bug if that’s what this is (it seems to be). Is there anything I’m missing?

#2

Ought to be able to, since it’s not really negative in any sense.

It’s almost certainly a bug. Are you targeting just Cocoa? or do you need support for other platforms?

#3

I’m just targeting Cocoa, didn’t try in Carbon. But I’ve created a bug report, and included a simple sample project that shows the problem.
