Utility for converting Shift-JIS encoded files to UTF-8 encoded files

Question

My client has a ton of Japanese text files which are encoded in Shift-JIS.

They need a utility which can convert these files to UTF-8.

Ideally, the tool would offer both command-line and interactive options.

Any suggestions?

(PS - could someone with rep add the "shift-jis" tag?)

Answer 1

iconv (or iconv, as the case may be).
