- "C" / "Other"
- "L" / "Letter"

パラメータ
-
property -
調べたい Unicode プロパティ (定数 IntlChar::PROPERTY_* を参照ください)。
If out of range, or this method doesn't work with the given value,
FALSEis returned. -
value -
Selector for a value for the given property. If out of range,
FALSEis returned.In general, valid values range from 0 up to some maximum. There are a couple exceptions:
-
IntlChar::PROPERTY_BLOCKvalues begin at the non-zero valueIntlChar::BLOCK_CODE_BASIC_LATIN -
IntlChar::PROPERTY_CANONICAL_COMBINING_CLASSvalues are not contiguous and range from 0..240.
-
-
nameChoice -
Selector for which name to get. If out of range,
FALSEis returned.All values have a long name. Most have a short name, but some do not. Unicode allows for additional names; if present these will be returned by adding 1, 2, etc. to
IntlChar::LONG_PROPERTY_NAME.
返り値
Returns the name, or FALSE if either the property or the nameChoice
is out of range.
If a given nameChoice returns FALSE, then all larger values of nameChoice
will return FALSE, with one exception: if FALSE is returned for IntlChar::SHORT_PROPERTY_NAME,
then IntlChar::LONG_PROPERTY_NAME (and higher) may still return a non-FALSE value.
