Confusingly, my browser renders that symbol () as a... square.
Chrome, it's a 't' surrounded by italicized parentheses. Unsuccessfully searched for unicode lookup to find the text description of the character. Edit: at http://www.fileformat.info/info/unicode/char/search.htm?q=%E... I found: Not sure what to make of it. Apple decided to assign to a Unicode character their logo. Does anyone have context?
Might be for compatibility with MacRoman, which also had such a character.
