The most commonly used escape character is is >. These escaped characters can be used in HTML like normal characters without causing syntax errors or parsing exceptions.

In addition to , HTML also provides many other escape characters, such as:

& means & symbol
" means double quotation marks
' means Single quotation mark
represents a space character
© represents a copyright symbol
® represents a registered trademark symbol
™ represents a trademark symbol
