Question 1

What does encoding do?

Accepted Answer

It replaces the five characters that matter in HTML — &, <, >, " and ’ — with their entity equivalents, so they display as text instead of being interpreted as markup.

Question 2

Which characters are escaped?

Accepted Answer

Ampersand, less-than, greater-than, double quote and single quote. These are the ones that can break HTML or change how a page renders.

Question 3

How is decoding done?

Accepted Answer

The browser’s own HTML parser is used to convert both named entities like &lt; and numeric entities like &#60; back into characters.

Question 4

Is my text sent anywhere?

Accepted Answer

No. Encoding and decoding happen entirely on your device.
