Unescaping UTF-8 Strings in Ruby 1.9
Today Radar and I encountered a little issue
String encodings in Ruby 1.9. In this project, some Merb UTF-8
params needed to be unescaped. We spent some trying to force strings
into UTF-8 encoding but for some reason while the encoding was UTF–8,
the actual contents of the strings were getting massacred.
Long story short:
# In Ruby 1.9
puts URI::unescape # => "Baden-WÃ¼rttemberg"
puts CGI::unescape # => "Baden-Württemberg"
Another lesson we learnt on our adventures today is the following:
m1 = "Munich"
puts = m1.encoding # let's suppose it is something other than UTF-8, such as ASCII-8Bit
m2 = "München"
puts = m2.encoding # let's suppose we have a UTF-8 encoded string
# The following will raise an exception about mismatched encodings
m3 = m1 << m2
# The easiest way to get around this is to do the concatenation like so:
m3 = m3 = m1 << m2.force_encoding
