Non-Roman is also known as CJK-capable, that is, capable of handling multi-byte character sets, such as Chinese, Japanese, or Korean.
Host encoding is a platform-dependent encoding for the host machine. For non-UNIX Roman systems, it is MacRomanEncoding in Mac OS and WinAnsiEncoding in Windows. In UNIX (except HP-UX) Roman systems, it is ISO8859-1 (ISO Latin-1); for HP-UX, it is HP-ROMAN8. See Appendix D in the PDF Reference for descriptions of MacRomanEncoding, WinAnsiEncoding, and PDFDocEncoding.
For non-Roman systems, the host encoding may be a variety of encodings, which are defined by a CMap (character map). See Section 5.6.4 in the PDF Reference for a list of predefined CMaps.
