Details:

When gpinyin interpolates an apostrophe before one of the vowels [aeo], it
uses the \[aq] special character, which is of neutral shape.  However, this
appears to be incorrect, as it is for apostrophes in typeset English.

For example, a majority the many font examples at
<http://pinyin.info/news/category/misc/pinyin-font-misc/> use discernibly
non-neutral glyphs for this purpose.

Our nroff device (grotty) can and does degrade this special character to an
ASCII apostrophe if necessary.  (It's something of an academic point, as only
-Tutf8 has a sufficient character repertoire to handle gpinyin output in
general.)
