lib: replace \u2019 with regular ascii quote

The previous commit stores baked-in files with non-ASCII characters
as UTF-16.  Replace the \u2019 with a regular quote character so that
the files they're in can be stored as one-byte strings.  The UTF-16
functionality is still tested by the Unicode diagram in lib/timers.js.
