The magic number is ＭＳ明朝 encoded in CP932

PDF 1.6 Reference APPENDIX H Compatibility and Implementation Notes
Sections 3.2.4
{quote}5. In Acrobat 4.0 and earlier versions, a name object being treated as
text is
typically interpreted in a host platform encoding, which depends on the
operating system and the local language. For Asian languages, this
encoding may be something like Shift-JIS or Big Five. Consequently, it is
necessary to distinguish between names encoded this way and ones
encoded as UTF-8. Fortunately, UTF-8 encoding is very stylized and its
use can usually be recognized. A name that does not conform to UTF-8
encoding rules can instead be interpreted according to host platform encoding.

Are there any method to detect the magic host platform encoding?
