9.13.4 Coping with FrameMaker index-entry conversion defects
If you are working with files converted from an older version of FrameMaker to version 8.0 or later, you might encounter a FrameMaker defect. When FrameMaker converts a pre-8.0 file, it converts the content to Unicode in UTF-8 encoding. However, the index markers are not converted correctly, at least for Japanese and probably for all DBCS encodings (Chinese, Korean). Instead of converting character by character, FrameMaker converts byte by byte, encoding each byte of each double-byte character in UTF-8 individually. This is not valid in any sense, and is not a recoverable error. You will have to correct these problems in FrameMaker.
