It is a mistake. 
Namazu doesn't support UTF-8.

It is a mistake. 
Namazu doesn't support UTF-8. 
(But, it corresponds to the document of ja_JP.UTF-8.)

It is necessary to keep the following. 

$ mknmz --indexing-lang=ja_JP.eucjp -k -e ...

The document of ISO-2022-JP, Shift_JIS, and EUC-JP can be handled 
though it is specified ja_JP.eucjp. 

--indexing-lang option doesn't specify the encoding of the 
handled document.

The retrieval key word supports only ISO-2022-JP, Shift_JIS, 
and EUC-JP. 
(UTF-8 is a unsupport. Therefore, it is recommended to convert it 
into EUC-JP like this example. )

The retrieval result is sure to become EUC-JP. (for UNIX)
