- * NKF - Ruby extension for Network Kanji Filter
- *
- * == Description
- *
- * This is a Ruby Extension version of nkf (Network Kanji Filter).
- * It converts the first argument and returns converted result. Conversion
- * details are specified by flags as the first argument.
- *
- * *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 or UTF-16.
- *
- * 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 and UTF-16.
- * 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>, <b>-x</b> or <b>-S</b>.
- *
- * == Flags
- *
- * === -b -u
- *
- * Output is buffered (DEFAULT), Output is unbuffered.
- *
- * === -j -s -e -w -w16 -w32
- *
- * Output code is ISO-2022-JP (7bit JIS), Shift_JIS, EUC-JP,
- * UTF-8N, UTF-16BE, UTF-32BE.
- * Without this option and compile option, ISO-2022-JP is assumed.
- *
- * === -J -S -E -W -W16 -W32
- *
- * Input assumption is JIS 7 bit, Shift_JIS, EUC-JP,
- * UTF-8, UTF-16, UTF-32.
- *
- * ==== -J
- *
- * Assume JIS input. It also accepts EUC-JP.
- * This is the default. This flag does not exclude Shift_JIS.
- *
- * ==== -S
- *
- * Assume Shift_JIS and X0201 kana input. It also accepts JIS.
- * EUC-JP is recognized as X0201 kana. Without <b>-x</b> flag,
- * X0201 kana (halfwidth kana) is converted into X0208.
- *
- * ==== -E
- *
- * Assume EUC-JP input. It also accepts JIS.
- * Same as -J.
- *
- * === -t
- *
- * No conversion.
- *
- * === -i_
- *
- * Output sequence to designate JIS-kanji. (DEFAULT B)
- *
- * === -o_
- *
- * Output sequence to designate ASCII. (DEFAULT B)
- *
- * === -r
- *
- * {de/en}crypt ROT13/47
- *
- * === \-h[123] --hiragana --katakana --katakana-hiragana
- *
- * [-h1 --hiragana] Katakana to Hiragana conversion.
- *
- * [-h2 --katakana] Hiragana to Katakana conversion.
- *
- * [-h3 --katakana-hiragana] Katakana to Hiragana and Hiragana to Katakana conversion.
- *
- * === -T
- *
- * Text mode output (MS-DOS)
- *
- * === -l
- *
- * ISO8859-1 (Latin-1) support
- *
- * === -f[<code>m</code> [- <code>n</code>]]
- *
- * Folding on <code>m</code> length with <code>n</code> margin in a line.
- * Without this option, fold length is 60 and fold margin is 10.
- *
- * === -F
- *
- * New line preserving line folding.
- *
- * === \-Z[0-3]
- *
- * Convert X0208 alphabet (Fullwidth Alphabets) to ASCII.
- *
- * [-Z -Z0] Convert X0208 alphabet to ASCII.
- *
- * [-Z1] Converts X0208 kankaku to single ASCII space.
- *
- * [-Z2] Converts X0208 kankaku to double ASCII spaces.
- *
- * [-Z3] Replacing Fullwidth >, <, ", & into '&gt;', '&lt;', '&quot;', '&amp;' as in HTML.
- *
- * === -X -x
- *
- * Assume X0201 kana in MS-Kanji.
- * With <b>-X</b> or without this option, X0201 is converted into X0208 Kana.
- * With <b>-x</b>, try to preserve X0208 kana and do not convert X0201 kana to X0208.
- * In JIS output, ESC-(-I is used. In EUC output, SSO is used.
- *
- * === \-B[0-2]
- *
- * Assume broken JIS-Kanji input, which lost ESC.
- * Useful when your site is using old B-News Nihongo patch.
- *
- * [-B1] allows any char after ESC-( or ESC-$.
- *
- * [-B2] forces ASCII after NL.
- *
- * === -I
- *
- * Replacing non iso-2022-jp char into a geta character
- * (substitute character in Japanese).
- *
- * === -d -c
- *
- * Delete \r in line feed, Add \r in line feed.
- *
- * === \-m[BQN0]
- *
- * MIME ISO-2022-JP/ISO8859-1 decode. (DEFAULT)
- * To see ISO8859-1 (Latin-1) -l is necessary.
- *
- * [-mB] Decode MIME base64 encoded stream. Remove header or other part before
- * conversion.
- *
- * [-mQ] Decode MIME quoted stream. '_' in quoted stream is converted to space.
- *
- * [-mN] Non-strict decoding.
- * It allows line break in the middle of the base64 encoding.
- *
- * [-m0] No MIME decode.
- *
- * === -M
- *
- * MIME encode. Header style. All ASCII code and control characters are intact.
- * Kanji conversion is performed before encoding, so this cannot be used as a picture encoder.
- *
- * [-MB] MIME encode Base64 stream.
- *
- * [-MQ] Perform quoted encoding.
- *
- * === -l
- *
- * Input and output code is ISO8859-1 (Latin-1) and ISO-2022-JP.
- * <b>-s</b>, <b>-e</b> and <b>-x</b> are not compatible with this option.
- *
- * === \-L[uwm]
