Issue #1098 has been updated by Yui NARUSE.

Category set to M17N
Status changed from Open to Rejected
Assigned to set to Yui NARUSE

You declared in magic comment as CP850, but your exact script encoding seems ISO-8859-1.

Your character: U+00DF (Latin Small Leter Sharp S) is,
\xDF in ISO-8859-1
\xE1 in CP850

"\xdf".encode("iso-8859-1","CP850")
Encoding::UndefinedConversionError: "\xE2\x96\x80" from UTF-8 to ISO-8859-1 in conversion from CP850 to ISO-8859-1
        from (irb):24:in `encode'
