Frequently asked questions

When should I use named versus numeric entities?

Named entities like © are easier to read; numeric like © work universally even in legacy XML where only a small set of names exist. Numeric is the safest choice for non-HTML contexts.

Which characters absolutely need encoding?

Inside HTML you must escape &, <, >, and inside attributes also " and '. Failing to escape these is a common source of XSS vulnerabilities.

Will the encoder handle emoji and astral characters?

Yes. Characters outside the Basic Multilingual Plane are encoded as their full unicode code point, for example &#128512; for the grinning face emoji.

Is my input uploaded anywhere?

No. Encoding and decoding happen locally in JavaScript, so secrets in your HTML stay on your device.
