Ruby, delete null values of a string

Question

Example:

String test="hi\000\000\000"

Problem: Some methods require a string to be without nulls, how can I delete all null values of a string?

.split("\000",1) gives me an error: 'force_encoding' method doesn't exist
.gsub('\000','') does nothing

Answer 1

Even more simple:

test.delete("\000")

Answer 2

Try using double quotes, so test.gsub("\000", '').

Answer 3

Right now I tried this in JRuby and it worked:

test.gsub(/\000/, '')

Note that I am using a regex in the gsub and not a string.
