Перевод - Английский-Японский - Leon

As in the movie title.

Note: this is the Japanese pronunciation of the French pronunciation of Leon. The English Lee-awn would be written in Japanese as

リーアン

(On a personal note, I write my name Ian as
イーエン
and not with the usual Japanese version
イアン
because the former is really what my name sounds like in English, the latter sounds French.)

Anyway, for what it's worth. Caveat emptor! ^^
