画像のようにslickの矢印部分が文字化けしてしまいます。
どこを直せばよいかわかる方いますか？

また、chromeで検証するとこのように文字化け部分が表示されます

ご提示のコードは正しいものですか？DOCTYPE宣言等2回ありますが？

行動規範の内容に同意します

初めまして、こんばんは。

検証画面で文字化けがおこっている通り、擬似要素のcontentに矢印が記号のまま入っていることが原因かと思います。
文字化けを防ぐためにHTMLやCSS内では記号や特殊文字を用いる場合、極力10進数や16進数、文字実体参照を用いて書くべきです。
← を ← 、→ を → に変えてみてください。

少しでも参考になれば幸いです。
