Kconv.guess(str) → integer

Guess input encoding by NKF.guess2

[Source]

# File nkf/lib/kconv.rb, line 213
  def guess(str)
    ::NKF::guess(str)
  end

Kconv.guess_old(str) → integer

Guess input encoding by NKF.guess1

  end

Kconv.iseuc(str) → obj or nil

Returns whether input encoding is EUC-JP or not.

Note don‘t expect this return value is MatchData.

  def iseuc(str)
    RegexpEucjp.match( str )
  end

Kconv.issjis(str) → obj or nil

Returns whether input encoding is Shift_JIS or not.

Note don‘t expect this return value is MatchData.

Kconv.kconv(str, out_code, in_code = Kconv::AUTO)

Convert str to out_code. out_code and in_code are given as constants of Kconv.

Note This method decode MIME encoded string and convert halfwidth katakana to fullwidth katakana. If you don‘t want to decode them, use NKF.nkf.
