The short answer is that US-ASCII is correct for what you have asked Tidy 
to create.

The charset parameter specifies how to interpret "high-bit" characters, 
i.e. those that fall outside the basic US-ASCII character set (which is a 
common subset of all the valid charsets, apart from the EBCDIC-based ones 
that you hardly ever see).

With no overrides, Tidy will be creating "7-bit" output, and replacing 
all "extended" characters by their entity names or numeric equivalents. 
There will not be any "high-bit" bytes present, so it is not appropriate 
to specify how they should be interpreted.

If you really need "8-bit" output, there is a limited selection of 
parameters to force Tidy to use particular character sets. I don't think 
EUC-JP is one of them, though.
