Guess, ¤ (\u00A4) is the "localized currency symbol" defined in the
"International Components for Unicode" Library (ICU)
<http://unicode.org/reports/tr35/tr35-6.html#Number_Format_Patterns> - and a
valid character. But admittedly, it looks strange. ;)

According your project, you use a *localized* currency number formatter (in IB
there is a check-box where you can set/unset this). The currency symbol must
then match those defined in your current locale. That is, "$123.00" works only
if your currency symbol for your current locale is "$" as well. You probably
don't want this behavior, since on any other computer, the currency symbol can
be different - for example on my Mac I would have to type "€" for the symbol.

Since I don't know what IB is doing exactly, do it programmatically. Here is
the code which may solve your issue:
NSNumberFormatter* priceFormatter = [[NSNumberFormatter alloc] init];
[priceFormatter setFormat:@"$#,##0.00;$0;-$#,##0.00"];
[priceField setFormatter: priceFormatter];
[priceFormatter release];
Note that, here in this example, the currency symbol is fixed and equals to
"$".
It is not required to explicitly type the currency symbol, eg.: "123" ->
$123.00 Parsing works also if you type it in correctly say, "$123" -> "$123.00".
