Use curly quotes from the current font, removing an override that
switched to a Chinese font for those 4 characters. On all platforms,
this caused the quotes to differ in size and weight from the
surrounding text. On Linux, it also caused text to fall back to a
serif font rather than the intended sans-serif font. On Windows,
it used a full-width Chinese character, making it look like there
were extra spaces in the text. Typographic apostrophes, in
particular, appeared to have two or more extra spaces after them.
