money_format() function showing � instead of local currency symbol (pound)

Does anyone have any idea why money_format() is showing � instead of pound sign (£).

The function performs fi开发者_JS百科ne on my local server, but when I upload it to my remote server if renders incorrectly.

Does anyone know a solution?

You need to use £, not £

Quoted from Gumbo

The character � is the REPLACEMENT CHARACTER (U+FFFD). It is used when there was an error within an UTF code:

FFFD � REPLACEMENT CHARACTER

used to replace an incoming character whose value is unknown or unrepresentable in Unicode
