Accepts input with separators based on user's Locale. For example,
with a European locale, "1.234,56" is valid input. With a US locale,
"1,234.56" is accepted. The grouping separator is ignored and
removed, and the decimal separator is kept.
Supports multi-byte decimal separator and grouping separators.
The keypad localization is based on the user's Language setting,
but the separators come from the Formatting. Thus if the Language
is set to English, but the Formatting is set to, for example,
German, the keypad will show '.', but when pressed it will emit
',' to match the number Formatting. Otherwise the keypad breaks
the localized formatting.
