String objects may be created using String::new or as literals. byte by byteĮspana_utf8 = Įspana_utf8.pack( ' c* ').force_encoding( ' utf-8 ') class String A String object holds and manipulates an arbitrary sequence of bytes, typically representing characters. ASCII is an encoding with one-byte chars, so in examples in your question methods bytes and codepoints return the same values, coincindentally. ![]() u 687D u 6874' ' u 6870 u 687B u 6871 u 6844 u 687B u 698D u 6857 u 6878' ' u 684F u 6868' mystring. Ruby uses utf-8 encoding by default now and utf-8 was specifically designed so that its first codepoints (0-127) are exactly the same as in ASCII encoding.
