Is "ne" used as a pronunciation for any character except 呢? I am wondering about the Pinyin syllable ne (specifically, nè), because it is the ending of the name of a friend of mine. We are searching for a Chinese character that accurately represents this sound -- 那 is too strong because it sounds like na and I am not sure if 呢 is really appropriate for a name.

Are there any characters appropriate for a name that have this sound ne or nè?
I think you could reference the name Zinedine，Zidane, which has been translated as 齐内迪纳, 齐达内.

So, you can use either 内 or 纳 to transliterate ne.
