Chinese text (and most non-Western text) can't be represented in MacRoman. As a general rule, this method of drawing text is highly discouraged, at minimum because of its limited text support. > What is the recommended approach for taking an NSString* of text and drawing > it to a CGContextRef where the text may contain characters of any language? For simple needs, the NSString additions (on either Mac OS X or iOS) would be recommended. There are platform specific methods for making a CGContextRef current. For more complex needs, NSLayoutManager (Mac OS X only) or Core Text (both) can be used as well. -- David Duncan _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
