Constants:

• public const string FORMAT
  This is the platform dependent conversion specifier for scanning and printing values of type uint32.
• public const string FORMAT_MODIFIER
  The platform dependent length modifier for conversion specifiers for scanning and printing values of type int32 or uint32.
• public const int MAX_DECOMPOSITION_LENGTH
  The maximum length (in codepoints) of a compatibility or canonical decomposition of a single Unicode character.

Static methods:

• public static unichar max (unichar a, unichar b)
  Calculates the maximum of a and b.
• public static unichar min (unichar a, unichar b)
  Calculates the minimum of a and b.

Methods:

• public UnicodeBreakType break_type ()
  Determines the break type of c.
• public unichar clamp (unichar low, unichar high)
  Ensures that x is between the limits set by low and high. If low is greater than high the result is undefined.
• public bool compose (unichar b, out unichar ch)
  Performs a single composition step of the Unicode canonical composition algorithm.
• public bool decompose (out unichar a, out unichar b)
  Performs a single decomposition step of the Unicode canonical decomposition algorithm.
• public int digit_value ()
  Determines the numeric value of a character as a decimal digit.
• public size_t fully_decompose (bool compat, unichar[] result)
  Computes the canonical or compatibility decomposition of a Unicode character.
• public UnicodeScript get_script ()
  Looks up the UnicodeScript for a particular character (as defined by Unicode Standard Annex #24).
• public bool isalnum ()
  Determines whether a character is alphanumeric.
• public bool isalpha ()
  Determines whether a character is alphabetic (i.
• public bool iscntrl ()
  Determines whether a character is a control character.
• public bool isdefined ()
  Determines if a given character is assigned in the Unicode standard.
• public bool isdigit ()
  Determines whether a character is numeric (i.
• public bool isgraph ()
  Determines whether a character is printable and not a space (returns false for control characters, format characters, and spaces).
• public bool islower ()
  Determines whether a character is a lowercase letter.
• public bool ismark ()
  Determines whether a character is a mark (non-spacing mark, combining mark, or enclosing mark in Unicode speak).
• public bool isprint ()
  Determines whether a character is printable.
• public bool ispunct ()
  Determines whether a character is punctuation or a symbol.
• public bool isspace ()
  Determines whether a character is a space, tab, or line separator ( newline, carriage return, etc.
• public bool istitle ()
  Determines if a character is titlecase.
• public bool isupper ()
  Determines if a character is uppercase.
• public bool iswide ()
  Determines if a character is typically rendered in a double-width cell.
• public bool iswide_cjk ()
  Determines if a character is typically rendered in a double-width cell under legacy East Asian locales.
• public bool isxdigit ()
  Determines if a character is a hexadecimal digit.
• public bool iszerowidth ()
  Determines if a given character typically takes zero width when rendered.
• public string to_string ()
  Converts the value to its equivalent string representation
• public int to_utf8 (string? outbuf)
  Converts a single character to UTF-8.
• public unichar tolower ()
  Converts a character to lower case.
• public unichar totitle ()
  Converts a character to the titlecase.
• public unichar toupper ()
  Converts a character to uppercase.
• public UnicodeType type ()
  Classifies a Unicode character by type.
• public bool validate ()
  Checks whether ch is a valid Unicode character.
• public int xdigit_value ()
  Determines the numeric value of a character as a hexadecimal digit.
