Method Detail

Returns the object representing the Unicode block containing the given character, or null if the character is not a member of a defined block.

Note: This method cannot handle supplementary characters. To support all Unicode characters, including supplementary characters, use the of(int) method.

Returns:

Returns the object representing the Unicode block containing the given character (Unicode code point), or null if the character is not a member of a defined block. Returns: Throws: Since: See Also:

Returns the UnicodeBlock with the given name. Block names are determined by The Unicode Standard. The file Blocks-<version>.txt defines blocks for a particular version of the standard. The Character class specifies the version of the standard that it supports.

This method accepts block names in the following forms:

1. Canonical block names as defined by the Unicode Standard. For example, the standard defines a "Basic Latin" block. Therefore, this method accepts "Basic Latin" as a valid block name. The documentation of each UnicodeBlock provides the canonical name.
2. Canonical block names with all spaces removed. For example, "BasicLatin" is a valid block name for the "Basic Latin" block.
3. The text representation of each constant UnicodeBlock identifier. For example, this method will return the BASIC_LATIN block if provided with the "BASIC_LATIN" name. This form replaces all spaces and hyphens in the canonical name with underscores.

Finally, character case is ignored for all of the valid block name forms. For example, "BASIC_LATIN" and "basic_latin" are both valid block names. The en_US locale's case mapping rules are used to provide case-insensitive string comparisons for block name validation.

If the Unicode Standard changes block names, both the previous and current names will be accepted.

Returns: Throws: Since:
