+
+
+nkf - Network Kanji Filter
+
+
+
+# SYNOPSIS
+
+
+
+nkf __[-butjnesliohrTVvwWJESZxXFfmMBOcdILg]__ __[___file ...___]__
+
+
+
+# DESCRIPTION
+
+
+
+__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 __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 __-X__, __-x__ or __-S__.
+
+# OPTIONS
+
+- __-J -S -E -W -W16 -W32 -j -s -e -w -w16 -w32__
+
+Specify input and output encodings. Upper case is input.
+cf. --ic and --oc.
+
+ - __-J__
+
+ ISO-2022-JP (JIS code).
+
+ - __-S__
+
+ Shift_JIS and JIS X 0201 kana.
+ EUC-JP is recognized as X0201 kana. Without __-x__ flag,
+ JIS X 0201 Katakana (a.k.a.halfwidth kana) is converted into JIS X 0208.
+ If you use Windows, see Windows-31J (CP932).

+ UTF-16.
+ B or L gives whether Big Endian or Little Endian.

+
+- __-X -x__
+
+With __-X__ or without this option, X0201 is converted into X0208 Kana.
+With __-x__, try to preserve X0208 kana and do not convert X0201 kana to X0208.
+In JIS output, ESC-(-I is used. In EUC output, SS2 is used.
