--------------------------------------------

             Summary: YAML can't parse some valid unicode characters
                 Key: JRUBY-6317
                 URL: https://jira.codehaus.org/browse/JRUBY-6317
             Project: JRuby
          Issue Type: Bug
          Components: Ruby 1.9.2, Ruby 1.9.3
    Affects Versions: JRuby 1.6.5
            Reporter: Charles Oliver Nutter
            Assignee: Thomas E Enebo


As shown in the comments for JRUBY-6200, JRuby's "Psych" wrapper around 
SnakeYAML can't handle some unicode characters. This may be a SnakeYAML bug, or 
something in YAML spec we don't know about:

{noformat}
system ~/projects/jruby $ jruby --1.9 -ryaml -e 'YAML.load("\ufffd".to_yaml)'
StreamReader.java:98:in `checkPrintable': unacceptable character '�' 
(0xFFFD) special characters are not allowed
in "<reader>", position 4
        from StreamReader.java:191:in `update'
        from StreamReader.java:63:in `<init>'
        from PsychParser.java:115:in `parse'
        from PsychParser$INVOKER$i$1$0$parse.gen:65535:in `call'
{noformat}

I'm filing this because the original cases in JRUBY-6200 are resolved, and this 
seems to be a separate issue that won't affect most people.
