答案：

The previous HTML standard (HTML 4) specified the ISO-8859-1 character set as the default. When HTML5 was released, the specification was updated to default to UTF-8. UTF-8 is a much more flexible character set, and can support languages from all over the world.

The React framework defaults to reading ISO-8859-1 characters. So, if we don’t tell it to use UTF-8 (which is what SAP Cloud Platform uses), React will not understand the characters and will throw several syntax errors.

The tag is now the recommended best practice in all HTML.要獲取更多Jerry的原創(chuàng)文章，請(qǐng)關(guān)注公眾號(hào)"汪子熙":
