| ERROR | schema and instance document have incompatible character sets |
| CAUSE | Parsed schema components were in a simple-type character set while the parsed instance document data was not. A simple-type character set is single-byte, not shift sensitive, and has no linguistic specials in use. |
| ACTION | Reinitialize the schema global context with appropriate parser context settings, i.e. pass a parser context with its output encoding set to be a multibyte or Unicode character set. |
