I’m trying to draw localized text (i.e., the text could be in english, chinese, arabic, etc.) with character spacing and multiply blend mode (CGContextSetBlendMode, kCGBlendModeMultiply).

If I use CGContextShowTextAtPoint I’m able to adjust character spacing (CGContextSetCharacterSpacing) and blend mode (CGContextSetBlendMode, kCGBlendModeMultiply), but I get strange characters instead of the localized string.

If I use NSString drawAtPoint:withFont it works fine to draw the localized text but I’m not able to modify character spacing nor the blend mode. The strange thing is that I’m able to adjust the shadow with CGContextSetShadow. Thus, shouldn’t I be able to adjust the character spacing as well?

Is it possible to adjust character spacing and blend mode with NSString drawAtPoint:withFont? Or which encoding to use so that the localized text is showed correctly in all languages the the iPhone support?

iOS4 will be used.
