UILabel, UIFont and UTF-8 Triangle

问题

I'd like to use "BLACK RIGHT-POINTING TRIANGLE" (U+25B6) as a part of my UILabel's text. The label uses the system font (UIFont's systemFontOfSize:). The problem is that my triangle is rendered as a fancy image, not a "black right-pointing triangle". Is it possible to see the plain version?

Based on:

Unicode characters being drawn differently in iOS5

iOS 6 supports Unicode 6.1's variation selector, in this case \U0000FE0E. To answer my own question:

@"\U000025B6" // a fancy triangle (mapped to Emoji)
@"\U000025B6\U0000FE0E" // black right-pointing triangle

For more information check: http://www.unicode.org/versions/Unicode6.1.0/

Thanks @martin-r and @ACB, I wouldn't be able to figure this out without your hints!

In case someone doesn't have access to that devforums, the below mentioned line is the reply from Apple.

"With the set of fonts we ship in iOS, Hiragino Kaku Gothic ProN has the glyph you're looking for."

Try to use that particular font. That is the only way available now.
