Q: When sending a message with a $ character some handsets display this as an upside down question mark "¿" <00BF> character, why is this?

A: The HTTP API supports both '$' and '\u00A4'. Previously the user had to put in the character encoding \u00A4 for it to work properly. On older systems you will need to put '\u00A4' not 'u00A4' in the text.


Q: Is $ character <0024> ie /u0024 like in UTF-8?

A: No, for SMS Unicode encoding is /u00A4.
