"N" / "Number"

"P" / "Punctuation"

"S" / "Symbol"

The Unicode property to lookup (see the IntlChar::PROPERTY_* constants).

If out of range, or this method doesn't work with the given value, IntlChar::PROPERTY_INVALID_CODE is returned.

name

The value name to be matched. The name is compared using "loose matching" as described in PropertyValueAliases.txt.

返回值
