IntlChar::getPropertyValueName

Returns the Unicode name for a given property value, as given in the Unicode database file PropertyValueAliases.txt.

Note:

Some of the names in PropertyValueAliases.txt can only be retrieved using IntlChar::PROPERTY_GENERAL_CATEGORY_MASK, not IntlChar::PROPERTY_GENERAL_CATEGORY. These include:

• "C" / "Other"
• "L" / "Letter"
• "LC" / "Cased_Letter"
• "M" / "Mark"
• "N" / "Number"
• "P" / "Punctuation"
• "S" / "Symbol"
• "Z" / "Separator"

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

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

Selector for a value for the given property. If out of range, FALSE is returned.

In general, valid values range from 0 up to some maximum. There are a couple exceptions:

• IntlChar::PROPERTY_BLOCK values begin at the non-zero value IntlChar::BLOCK_CODE_BASIC_LATIN
• IntlChar::PROPERTY_CANONICAL_COMBINING_CLASS values are not contiguous and range from 0..240.

Selector for which name to get. If out of range, FALSE is 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.

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.
