+B<Nkf> is a yet another kanji code converter among networks, hosts and terminals.
+It converts input kanji code to designated kanji code
+such as ISO-2022-JP, Shift_JIS, EUC-JP, UTF-8, UTF-16 or UTF-32.
+
+One of the most unique faculty of B<nkf> is the guess of the input kanji encodings.
+It currently recognizes ISO-2022-JP, Shift_JIS, EUC-JP, UTF-8, UTF-16 and UTF-32.
+So users needn't set the input kanji code explicitly.
+
+By default, X0201 kana is converted into X0208 kana.
+For X0201 kana, SO/SI, SSO and ESC-(-I methods are supported.
+For automatic code detection, nkf assumes no X0201 kana in Shift_JIS.
+To accept X0201 in Shift_JIS, use B<-X>, B<-x> or B<-S>.
