AlliumCepa: Thank you for your sincere advice.
The person has become impossible to reply about it.
But it is the original text that I think has heard as a story of Poland or Czech Republic.
I try to investigate it.

Someone who knows the story, please teach me, it's good by Bulgarian language.

AlliumCepa: Thank you very much for your help.
I'm sorry. I have typed mistake "dose" in. The confusion seems not to have happened.
I was taught "Po,dlexjeq l.does smfkiur me,beujkf"="Здравейте, владея японски перфектно" by two Bulgarians. I could not understand the conversion rule in two sentences, even by the Web sites you taught.

Please! Could you instruct me in?

AlliumCepa: I received a message of "Po,dlexjeq l.does smfkiur me,beujkf" from a Bulgarian.
I look "Po,dlexjeq l.does smfkiur me,beujkf" = "Po,dlexjeq l.dose smfkiur me,beujkf". My typing sentence is after one. Copied one is before.

I am suspecting confusion of computer character's code.

Do you see equal them?

RockAda:I am interested in a Bulgarian language. I want to know the conversion rule from the Cyrillic alphabets to the Latin alphabets in Bulgarian.
Would you please teach me or teach Web pages wrote about it?

RockAda: Благодаря. Разбрах много добре.

Please teach me someone. What meaning of "Po,dlexjeq l.does smfkiur me,beujkf" ?
