I am not familiar with the API you are using, I use my own XML generator/parser, but it may be worth nothing something about XML. XML files are implicitly Unicode and generally UTF-8. So you cannot put an arbitrary sequence of bytes into XML as a string. A curly quote is not in the low Latin (<=127) range so it must be a multibyte value.
Clearly there are different API approaches possible on encoding: - convert an input encoding to UTF-8 - accept and write UTF-8 with validation, rejecting bad UTF-8 sequences - accept and write UTF-8 with validation, converting bad UTF-8 sequences silently to something else - accept and write UTF-8 without validation, potentially writing malformed XML Parsers have similar choices to make. But anyway, if your data is not valid UTF-8, it would explain why you get disastrous results. XML has no standard binary representation for anything other than Unicode strings, so symmetric encoding/decoding of such data, following your own invention or some extension to basic XML, is the only way. A low level XML API cannot be expected to offer this, especially one intended to write XML for consumption by other software. (This is in addition to the five characters prohibited in strings because they are XML markup).
