!! Summary
Use HTML entities to enter characters that cannot easily be typed on an ordinary keyboard. They take the form of an ampersand (`&`), an identifying string, and a terminating semi-colon (`;`), e.g. `&` for the ''&'' character.
!! Markup
```
The value of Tiddlers™ cannot even be expressed in £, € or $.
