Hi everybody, I get confused about some PDF specials. I know I could add ++++++++++++++++++++++++ \enableregime[utf] \PDFunicodetrue \input spec-tst.tex ++++++++++++++++++++++++ at the top of my source file so that I can use unicode characters in \comment or something alike. But when I used some macros inside \comment, like \comment[chapter \chinesenumber{1}]{\getmarking[chapter][current]} everything went wrong (this is a Chinese book). It seems that \sanitizePDFencoding\AAA\to\BBB will work only when \AAA is text. Meanwhile, \uchar{86}{222} and 回 should be the same, but the first generates error while the second one works fine. It's like there's something very mysterious that take care of the characters. How could I filter the macro and get the text string? Currently, I just wanna know how to get \uchar{86}{222} or \chinesenumber{counter} work as if they are really texts. -- Best Regards Chen ---------------------------------------------------------------- Zhi-chu Chen | Shanghai Synchrotron Radiation Facility No. 2019 | Jialuo Rd. | Jiading | Shanghai | P.R.
