Hello
I have a different return value from a method when the last line is
either
str.encode ''UTF-8''
return str.encode ''UTF-8'' # or:
str.encode! ''UTF-8''
In the first case the string is not in UTF-8! Both other return a
correct string. I changed this several times back and forth and tried it
again because I could not believe it. It really behaves like this.
This strange problem occurs with the following routine:
def convert2utf8 str, charset
str.force_encoding charset
rescue
str.force_encoding(''BINARY'').gsub!(Regexp.new(''[\x00-\x08\x0B\x0C\x0E-\x1F0\x80-\xFF]'',nil,''n''),
''.'')
ensure
str.force_encoding(''BINARY'').gsub!(Regexp.new(''[\x00-\x08\x0B\x0C\x0E-\x1F\x80-\xFF]'',nil,''n''),
''.'') unless str.valid_encoding?
str.encode ''UTF-8''
end
When ''str'' (comes from an email parsed with Mail 2.2.15 so
str.encoding
returns #<Encoding:US-ASCII>) consists of ISO-8859-1 encoded string and
''charset'' is ''ISO-8859-1'' this happens in a
Rails controller. I cannot
reproduce this in plain irb (will try in Rails console tomorrow). So is
this a Rails problem? Kinda ''lazy encode'' problem or
something?
Regards, T.

The latter two alternatives work, either because the change what is being returned to be what you want, or because they modify the string in place For example, if def foo 1 ensure 2 end then foo() evaluates to 1, not 2 Fred> Regards, T. > > -- > Posted viahttp://www.ruby-forum.com/.-- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

I didn''t test it with an ensure clause. So I feel the floor under my feet is still solid.
