U+2019 and U+00B4 are two different characters, both exist in Unicode.
The one in the string is U+2019, which is not representable in

You are right that toCString will convert the string to ISO-8859-1,
but it does so very simply by simply stripping the Unicode code-points
to 8-bits. That does the trick for ISO-8859-1, but for characters
outside of ISO-8859-1 it simply returns the lower byte instead of
either ignoring it or returning '?'. This could be seen as a bug, but
you would not get the original string anyway, as it's not possible to
encode it in ISO-8859-1.
