Notes

• You cannot reset convert table without restart.

• Though converter ignores letter what can be not interpret as a part of Roma-ji, remaining letters always be converted.

  $ python -m pyokaka.okaka
  Roman >>> Oh dear, this is English!
  JKana ... おh であr, tひs いs えんglいsh!
  

• Hyphen always be replaced with Cho'onpu.

  $ python -m pyokaka.okaka
  Roman >>> Roma-ji
  JKana ... ろまーじ
  

• Converter never analyze sentence structure. So it cannot recognize 'wa', 'o' and 'e' as postpositional particle.

  $ python -m pyokaka.okaka
  Roman >>> Watashi wa depa-to e enpitsu o kai ni ikimashita.
  JKana ... わたし わ でぱーと え えんぴつ お かい に いきました.
  

• Conversion is based on greedy algorithm. Single quote can be used as separater if you need.

  Roman >>> honya
  JKana ... ほにゃ
  Roman >>> honnya
  JKana ... ほっにゃ
  Roman >>> honnnya
  JKana ... ほんにゃ
  
  Roman >>> hon'ya
  JKana ... ほんや
