Indeed, the safe-charsets property of the utf-8 coding-system has not been updated to list the extra charsets it can now encode. In the trunk utf-8.el says: '((safe-charsets ascii eight-bit-control eight-bit-graphic latin-iso8859-1 latin-iso8859-15 latin-iso8859-14 latin-iso8859-9 hebrew-iso8859-8 greek-iso8859-7 cyrillic-iso8859-5 latin-iso8859-4 latin-iso8859-3 latin-iso8859-2 vietnamese-viscii-lower vietnamese-viscii-upper thai-tis620 ipa ethiopic indian-is13194 katakana-jisx0201 chinese-sisheng lao mule-unicode-0100-24ff mule-unicode-2500-33ff mule-unicode-e000-ffff) where in the RC branch it only says '((safe-charsets ascii eight-bit-control eight-bit-graphic latin-iso8859-1 mule-unicode-0100-24ff mule-unicode-2500-33ff mule-unicode-e000-ffff) And turning on unify-8859-on-encoding-mode doesn't update the corresponding info either. I think Dave or Handa would now better how to fix that (whether unify-8859-on-encoding-mode should change the safe-charsets or whether it should simply always include the new charsets and load ucs-tables when needed. And also which charsets should be added). Thank you for pointing it out. Stefan
