ウィキからの引用 ( Em ダッシュ)

ASCII 文字セットのように、実際の em ダッシュが使用できない場合は、二重 ("--") または三重のハイフンマイナス ("---") が使用されます。Unicode では、em ダッシュは U+2014 (10 進数 8212) です。

Em ダッシュ文字は ASCII 文字セットの一部ではありません。

This character does not exist in ASCII, but only in Unicode, usually encoded by UTF-8.

In UTF-8, characters are encoded by 2- or 3-byte sequences (or occasionally longer), where none of the two or three bytes is a valid ASCII code, where all of them are outside the ASCII range of 0 through 127.

One suspects that the foregoing only partly answers your question, but if so then this is probably because your question is, inadvertently, only partly asked. For further details, you can extend your question with more specifics.
