Unicode Hex Input on OS X Leopard
On Twitter, a “Retweet” is how we pass along interesting content to our followers. For example:

Notice the “RT” prefix, indicating this is a “Retweet”. People also spell out “Retweet”, but RT seems to be far more popular. Note that Retweeting is not an official Twitter feature, it’s just something people do.
There is another way, however. Many people now use the recycle symbol ♺ to indicate Retweets. I think this looks nicer than the alternatives, although ♺ has drawbacks:
- It consumes three bytes, cutting into your 140 byte limit.
- It might not display properly. When I use Twhirl, ♺ shows up as an empty box. (This could be the font I’m using, I need to investigate further.)
Finding the ♺ Character
You won’t find ♺ on your keyboard. On OS X, you can go to Edit -> Special Characters... to bring up this screen:

After a lot of scrolling and searching, you’ll eventually find the “RECYCLING SYMBOL FOR GENERIC MATERIALS” as shown above.
Typing ♺ and Other Unicode Characters
Provided you know the Unicode hex value (♺ = 267A), you can directly type the character. Just do this:
- From the Apple menu, select
System Preferences... - Click on
International - Select the
Input Menutab - Scroll down and make these selections: U.S., U.S. Extended, and Unicode Hex Input

Via someone’s advice on Twitter, I found this blog entry explaining the same thing, but he (?) did not mention selecting “U.S. Extended”. Without that, this technique does not work.
Now, to create the ♺ symbol, hold option and type 267a.
Other notes:
- The Special Characters screen shows the hex values for characters in the tooltip for each character. Just hover your mouse pointer over the character for a few seconds.
- I found another article that says to hold down shift and option, but it works fine for me without the shift key.
- This bug may affect you.
Unicode symbols typically have a fairly descriptive name.
Thus, the search field will often yield exactly the results you need.
Example, if you had searched for «recyc», you would have quickly found all recycling characters.
I sometimes type in parts of word and see what a roll of the ⚅⚄⚂ turns up.
And in spite of also using OS X, my browser shows it as an interrogation simbol (plain “?”) so also character codification each one uses at his computer is important.
Not as nice, but RT works better than recycling symbol.
I’m now testing on a Vista machine:
- the symbol appears in the Twitter web interface
- the symbol does *not* work in Twhirl
- I cannot copy/paste the symbol into any Windows app, like Word…just shows a box
- I can’t find the symbol in the Character Map
Clearly the symbol is available in some fonts, because it works in the web browser. But overall this is a PITA for Windows users, so I’ll probably avoid it and stick with RT in Twitter.
You can always tell who the Mac users are; they’re the ones helpfully explaining some workaround they’ve discovered.
Dangit. I think you need the number pad to make this work. Another workaround: TextExpander shortcut.
