Method: String#each_codepoint

Defined in:

string.c

#each_codepoint {|integer| ... } ⇒ String #each_codepoint ⇒ Object

Passes the Integer ordinal of each character in str, also known as a codepoint when applied to Unicode strings to the given block. For encodings other than UTF-8/UTF-16(BE|LE)/UTF-32(BE|LE), values are directly derived from the binary representation of each character.

If no block is given, an enumerator is returned instead.

"hello\u0639".each_codepoint {|c| print c, ' ' }

produces:

104 101 108 108 111 1593

Overloads:

• #each_codepoint {|integer| ... } ⇒ String

  Yields:

  • (integer)

  Returns:

  • (String)
