Description

The offical documentation (http://www.ruby-doc.org/core-2.1.4/String.html#method-i-strip) says:
strip → new_str

Returns a copy of str with leading and trailing whitespace removed.

But

[9] pry(main)> "#{0.chr}#{9.chr}#{10.chr}#{11.chr}#{12.chr}#{13.chr}#{32.chr}" 
=> "\x00\t\n\v\f\r " 
[10] pry(main)> "#{0.chr}#{9.chr}#{10.chr}#{11.chr}#{12.chr}#{13.chr}#{32.chr}".length
=> 7
[11] pry(main)> "#{0.chr}#{9.chr}#{10.chr}#{11.chr}#{12.chr}#{13.chr}#{32.chr}".strip
=> "" 
([4] pry(main)> (0..255).each { |char| puts "char #{char} stripped" if char.chr.strip.empty? }
char 0 stripped
char 9 stripped
char 10 stripped
char 11 stripped
char 12 stripped
char 13 stripped
char 32 stripped

Stripped characters are

  1. Null char (0)
  2. Horizontal Tab (9)
  3. Line Feed (10)
  4. Vertical Tab (11)
  5. Form Feed (12)
  6. Carriage Return (13)
  7. Space (32)
