  • The string must contain a complete prefix and suffix. For example, if the pattern is * "{#};(#)", then "{123}" or "(123)" would match, but "{123", "123}", and "123" would all fail. * (The latter strings would be accepted in lenient mode.) *
  • Whitespace may not appear at arbitrary places in the string. In lenient mode, whitespace * is allowed to occur arbitrarily before and after prefixes and exponent separators. *
  • Leading grouping separators are not allowed, as in ",123". *
  • Minus and plus signs can only appear if specified in the pattern. In lenient mode, a plus * or minus sign can always precede a number. *
  • The set of characters that can be interpreted as a decimal or grouping separator is * smaller. *
  • If currency parsing is enabled, currencies must only appear where * specified in either the current pattern string or in a valid pattern string for the current * locale. For example, if the pattern is "¤0.00", then "$1.23" would match, but "1.23$" would * fail to match. *
