使用方法How to use
- 1粘贴文本。Paste text.
- 2选择「转义」或「还原」。Choose Escape or Unescape.
- 3复制结果。Copy the result.
说明Good to know
- 转义处理 & < > ，可选同时处理引号；还原支持数字实体和常见命名实体（& © 等），不认识的原样保留。Escape handles & < > and, optionally, quotes. Unescape understands numeric entities and the common named ones (& © …); unknown names are left as they are.
- 转义用于把文字安全放进 HTML，并不是对不可信网页代码的完整安全过滤。Escaping is for putting text safely into HTML. It is not a full security filter for untrusted markup.
