/*
* NKF - Ruby extension for Network Kanji Filter
*
* == Description
*
* This is a Ruby Extension version of nkf (Netowrk Kanji Filter).
* It converts the first argument and return 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
*
* Output code is ISO-2022-JP (7bit JIS), Shift_JIS, EUC-JP,
* UTF-8N, UTF-16BE.
* Without this option and compile option, ISO-2022-JP is assumed.
*
* === -J -S -E -W -W16
*
* Input assumption is JIS 7 bit, Shift_JIS, EUC-JP,
* UTF-8, UTF-16LE.
*
* ==== -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] Perfome 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]
*
* new line mode
* Without this option, nkf doesn't convert line breaks.
*
* [-Lu] unix (LF)
*
* [-Lw] windows (CRLF)
*
* [-Lm] mac (CR)
*
* === --fj --unix --mac --msdos --windows
*
* convert for these system
*
