Determine if this character is an ISO control character.

Determine if this character is a numeric digit. That is, if its Unicode general category is Nd.

The hash code for this Character, which is always its 32-bit Unicode code point.

The Unicode code point of the character, an Integer in the range 0..#10FFFF.

Determine if this character is a letter. That is, if its Unicode general category is Lu, Ll, Lt, Lm, or Lo.

Determine if this is a lowercase representation of the character. That is, if its Unicode general category is Ll.

The lowercase representation of this character.

Conversion of uppercase characters to lowercase is performed according to a locale-independent mapping that produces incorrect results in certain locales (e.g. tr-TR).

Furthermore, this conversion always produces a single character, which is incorrect for characters whose uppercase representation comprises multiple characters, for example İ. Thus,

• 'İ'.uppercased evaluates to 'i', whereas
• "İ".uppercased evaluates, more correctly, to the string "i̇".

Therefore, for most purposes, it is better to use char.string.lowercased instead of char.lowercased.

The character with the Unicode code point that is the predecessor of the unicode code point this character.

A string containing just this character.

The character with the Unicode code point that is the successor of the unicode code point this character.

Determine if this is a title case representation of the character. That is, if its Unicode general category is Lt.

The title case representation of this character.

Determine if this is an uppercase representation of the character. That is, if its Unicode general category is Lu.

The uppercase representation of this character, in the system default locale.

Conversion of lowercase characters to uppercase is performed according to a locale-independent mapping that produces incorrect results in certain locales (e.g. tr-TR).

Furthermore, this conversion always produces a single character, which is incorrect for characters whose uppercase representation comprises multiple characters, for example ß. Thus,

• 'ß'.uppercased evaluates to 'ß', whereas
• "ß".uppercased evaluates, more correctly, to the string "SS".

Therefore, for most purposes, it is better to use char.string.uppercased instead of char.uppercased.

Determine if this character is a whitespace character. The following characters are whitespace characters:

• LINE FEED, \n or \{#000A},
• FORM FEED, \f or \{#000C},
• CARRIAGE RETURN, \r or \{#000D},
• HORIZONTAL TABULATION, \t or \{#0009},
• LINE TABULATION, \{#000B},
• FILE SEPARATOR, \{#001C},
• GROUP SEPARATOR, \{#001D},
• RECORD SEPARATOR, \{#001E},
• UNIT SEPARATOR, \{#001F}, and
• any Unicode character in the general category Zs, Zl, or Zp that is not a non-breaking space.

Compare this character with the given character, according to the Unicode code points of the characters.

Determines if the given object is a character with the same code point as this character.

Determine if this character's code point is larger than the given character's code point, returning false if the two characters represent the same code point.

The indirect successor or predecessor at the given offset, where:

• x.neighbour(0) == x,
• x.neighbour(i+1) == x.neighbour(i).successor, and
• x.neighbour(i-1) == x.neighbour(i).predecessor.

Determine if this character's code point is smaller than or equal to the given character's code point, returning true if the two characters represent the same code point.

Determine if this character's code point is larger than or equal to the given character's code point, returning true if the two characters represent the same code point.

The difference between the Unicode code point of this character, and the Unicode code point of the given character.

The sign of the offset from the given value.

Determine if this character's code point is smaller than the given character's code point, returning false if the two characters represent the same code point.
