Ruby Output Unicode Character
In Ruby 1.9.x+
Use String#encode:
checkmark = "\u2713"puts checkmark.encode('utf-8')prints
✓In Ruby 1.8.7
puts '\u2713'.gsub(/\\u[\da-f]{4}/i) { |m| [m[-4..-1].to_i(16)].pack('U') }✓
falsetru's answer is incorrect.
checkmark = "\u2713"puts checkmark.encode('utf-8')This transcodes the checkmark from the current system encoding to UTF-8 encoding.(That works only on a system whose default is already UTF-8.)
The correct answer is:
puts checkmark.force_encoding('utf-8')This modifies the string's encoding, without modifying any character sequence.
In newer versions of Ruby, you don't need to enforce encoding. Here is an example with 2.1.2:
2.1.2 :002 > "\u00BD" => "½"Just make sure you use double quotes!
