The problem you're running into has to do with encoding mismatch
(under ruby 1.9) in some data you're munging/rendering in that view.
First thing you should do is check your config/setup regarding
encoding:
$ ./script/rails console...> __ENCODING__ => #<Encoding:UTF-8>
> Encoding.default_internal => #<Encoding:UTF-8>
> Encoding.default_external => #<Encoding:UTF-8>
> ActiveRecord::Base.configurations[Rails.env]["encoding"] => "utf8" ...
Assuming your stack is properly setup for utf-8, then the most likely
culprit is that you have some non-utf-8 binary char(s) in some data
that is causing the problem (probably copy/pasted from ms-word into
some form).
Not the same error, but here's an example of a similar encoding-
related problem:
> s = "foo™" => "foo™"
> s.encoding
=> #<Encoding:UTF-8>
> s.sub(/foo/, 'bar')
=> "bar™"
> s2 = "foo™".force_encoding("ASCII")
=> "foo\xE2\x84\xA2"
> s2.encoding
=> #<Encoding:US-ASCII>
> s2.sub(/foo/, 'bar')
ArgumentError: invalid byte sequence in US-ASCII
...
You can test/log the underlying data you're trying to render in that
view to see what exactly is causing the problem in order to delete/
replace it.
The bigger issue is ... how to prevent and/or deal with this
particular case when it happens again? Probably many diff ways to
deal with this, but in such cases where I need to force the encoding
to be valid utf-8 for a given submitted string no matter what, I've
used something like the following:
...
IC_UTF8 = Iconv.new('UTF-8//IGNORE', 'UTF-8')
...
def force_utf8(str)
#note added extra space plus chop to fix certain cases.
IC_UTF8.iconv("#{str} ")[0..-2]
end
...
> s2
=> "foo\xE2\x84\xA2"
> s2.encoding
=> #<Encoding:US-ASCII>
> s3 = force_utf8(s2)
=> "foo™"
> s3.encoding
=> #<Encoding:UTF-8>
> s3.sub(/foo/, 'bar')
=> "bar™"
