in pdf traditionally a string (that is, the ones that represented bookmarks and such) were in pdf doc encoding, so

that's still strings. However, at some point another notation was introduced:

<hex sequence>

which again is utf16

or a string using PDFDocEncoding. The <> notation can be used anywhere, where a PDF string is expected regardless of the encoding.

but this time hex encoded (less efficient but so seldom used that it does not really matter)

Not to forget: Some characters inside (...) need to be escaped (`\', unmatched `(' and `)', line ends, ...) Yours sincerely Heiko PS: Regarding encodings: hyperref has an undocumented option pdfencoding=auto Then the bookmark string is converted to Unicode (larger range of possible characters). Then hyperref tries a conversion to PDFDocEncoding (via package stringenc). Depending on the success, the bookmark string is then stored in PDFDocEncoding if possible and in Unicode otherwise.
