Today, Ryan Bigg and I encountered a little issue with 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

# Broken

# Working


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("UTF-8")
