Hi,  
I understood ISO-8859-16 was among the supported encoding but I get this  
error:

Encoding::ConverterNotFoundError: code converter not found for  
ISO-8859-16  
org/jruby/RubyString.java:7597:in `encode’

On this line:

code = code.encode(internal\_encoding) # internal\_encoding = ‘UTF-8’

I can read the file correctly with:

code = IO.read(path,{ :encoding =\> file\_encoding, :mode =\> ‘rb’}) #  
file\_encoding = ‘ISO-8859-16’

Any thoughts?

iso-8859-16 is supported in C Ruby from commit 33993 (Dec. 9th, 2011),  
please see  
[http://svn.ruby-lang.org/cgi-bin/viewvc.cgi/trunk/enc/trans/iso-8859-16-tbl.rb?view=log](http://svn.ruby-lang.org/cgi-bin/viewvc.cgi/trunk/enc/trans/iso-8859-16-tbl.rb?view=log).

It looks as if you used JRuby. Can you tell us which version?

It may be that JRuby didn’t yet implement ISO-8859-16. I have cc’ed the  
JRuby implementers to get their feedback.

Regards, Martin.

My bad, I was using JRuby 1.7.6, the problems do not appear with the  
original Ruby interpreter, version 2.0.

I have already opened an issue for JRuby.

More in details ruby 1.9.3 p 448 gives me this error:  
bugtest.rb:2:in `encode': code converter not found (ISO-8859-16 to UTF-8) (Encoding::ConverterNotFoundError) from bugtest.rb:2:in`’

Which seems to me more detailed in respect to the JRuby error.

Encoding::ConverterNotFoundError: code converter not found for  
ISO-8859-16  
encode at org/jruby/RubyString.java:7597  
(root) at bugtest.rb:2

Ruby 2.0 runs smoothly instead, no errors raised.

Thanks for the redirect, Martin.

It turns out OpenJDK does not support ISO-8859-16 in its builtin  
charsets, so I had to go ahead and implement one on my own. Fixed now  
for JRuby 1.7.7 and master.
