---------------------------------------
Summary: String#encode should not convert binary to mangled UTF-8
Key: JRUBY-6588
URL: https://jira.codehaus.org/browse/JRUBY-6588
Project: JRuby
Issue Type: Bug
Affects Versions: JRuby 1.6.7
Reporter: Bernerd Schaefer
Assignee: Thomas E Enebo
In Moped (my MongoDB driver), I have some code attempting to safely convert
input text into UTF-8 (which all strings must be).
See for a simplified test-case of the implementation:
https://gist.github.com/2351047
Problem: that calling encode('utf-8') on a binary string creates garbage utf-8
text instead of raising a conversion error like 1.9.
Reason the code exists: We're tracking referrers in our app, but the header
value in the rack environment is encoded as ASCII-8bit; this code then follows
the happy-path of calling `encode('utf-8')` and finally tries forcing the
encoding when that raises an error.
Tested on: jruby-1.6.7 and jruby-1.7.0-dev
