それが正常に動作して除いて.......ほぼ正確に何が必要ありません....それはやさしいUTF8されていませんが...私は意味...それは上（の部分に単語全体を分割します特別な文字）どこにすべきではない！

ので、私の推測では、私が...ではなく、正規にpreg_replaceの

をマルチバイト関数を使用する必要がありますされ2と3の単語のために私はmb_ereg_replaceとにpreg_replaceを交換しようとしたが、それが必要として、それが機能していません...少なくともありませんフレーズ

アイデア？

PCREはUTF-8を扱うことができます。それぞれの正規表現に/u修飾子を追加するだけです。

（あなたはまた、\w+の代わりに\pL+を使用することができますが、フラグは、最近のPCREのバージョンで十分です。）
