The IGES specification allows Kanji characters to be encoded as hexadecimal sequences in general note (type 212) entities. Other non-conforming IGES files may have literal 8-bit Shift JIS sequences in strings.

The IGES library will populate string attributes with these values as-is, without any character set translation, so that you can process them as they appear in the file.

When using the strings to populate STEP data, you may need to manually convert the values to UTF-8 representation so they will be written properly to STEP Part 21 files as ISO 10646 string data.
