gsub non ASCII character in Ruby

Question

I am trying to replace a non ASCII character from a string with the following code:

string.gsub(194.chr,'')

When I do this, I get the following error:

RegexpError: premature end of regular expression: / /

Can anyone tell me how to achieve this?

Answer 1

>> string="foo\xC2bar"
=> "foo\xC2bar"
>> string.force_encoding"ASCII-8BIT"
=> "foo\xC2bar"
>> string.gsub(194.chr, '')
=> "foobar"
