std::string OEToUTF8(const char *ptr,
                     const bool remove_markup = true)

Convert the string ‘ptr’, typically the output of the function OECreateIUPACName optionally post-processed by a language translation function, from the internal encoding, which uses \u escapes to represent non-ASCII characters, to UTF-8 character encoding.

The ‘remove_markup’ flag controls the disposition of italics, superscript, and subscript markup. If the value is ‘true’ (the default), the markup is removed. If ‘false’, the markup is left in the output string, which should be post-processed.
