Ruby has methods for working with different encoding systems. For example: "abc".encoding.name # "UTF-8" There are a few special scenarios where the current encoding (encoding.name) doesn’t match the actual encoding of the string. You can find this while reading data from a website, file, database or another external source.

In either case, English (ASCII) text is compatible with UTF-8, and Rails provides solid enough pure-Ruby UTF-8 support to get you most of the rest of the way. That said, anyone dealing with encodings other than UTF-8 and ISO-8859-1 (Japanese and Russian Rubyists) were definitely not in …

force_encoding is used to tell Ruby the encoding of a string that already has the correct bytes for that encoding (eg. a UTF-8 string read from a file in an ISO-8859-1 program).force_encoding will never modify the underlying bytes of a string. Example:
