self を NFC、NFD、NFKC、NFKD のいずれかの正規化形式で Unicode 正規化し た文字列に置き換えます。
...に発生します。
//emlist[例][ruby]{
text = "a\u0300"
text.unicode_normalize!(:nfc)
text == "\u00E0" # => true
text.unicode_normalize!(:nfd)

String
# unicode _ normalized?(form = :nfc) -> bool (9007.0) -
self が引数 form で指定された正規化形式で Unicode 正規化された文字列か どうかを返します。
...=> true
"\u00E0".unicode_normalized? # => true

"\xE0".force_encoding('ISO-8859-1').unicode_normalized?
# => Encoding::CompatibilityError raised
//}

String
# valid _ encoding? -> bool (9007.0) -
文字列の内容が、現在のエンコーディングに照らしあわせて妥当であれば true を返します。そうでない場合は false を返します。
