char-encoding: raw <= this is your problem.

Raw encoding is the tidy equivalent of "garbage in, garbage out".  When parsing, tidy converts everything (including named entities such as &nbsp;) into utf-8;  once the DOM is constructed and cleaned, it outputs everything in the requested encoding. Raw output doesn't create any entities (phrases beginning with & and ending with ;); since you have requested raw, it coverts the non-breaking space (stored internally in utf8) to it's numeric value, 160.

I don't know why you need to use raw encoding for asian character sets, but I really don't need to know because tidy has the option of specifying different input and output encodings.  Thus, if you specify:

input-encoding: raw
output-encoding: utf8

your input will be read just as it is now, but the output will be valid utf-8.  If you wanted unicode output you could use:

output-encoding: iso2022

If your version of tidy was built with support for asian encodings you should also be able to use:

output-encoding: shiftjis

or for the chinese big 5 character set:

output-encoding: big5

Other relevant output encodings include ASCII (to limit the output to 7-bit values), mac (to convert to the McIntosh Roman character set), win1252 (which uses otherwise invalid values in the 128-159 range), and latin-1 (probably the most common). With any of these encodings, characters which cannot be represented in the requested output character set are converted to entities.

I hope this helps.
