irb 0.9.5 for Windows:

irb(main):016:0\> puts ‘\c’  
irb(main):017:0’

i.e. irb expects a continuation line. Guess this is a bug?

In case someone has a more recent release of irb, does this still  
occur in the newer one?

You need to use double quotes " " instead of single quotes ’ ’  
because you’re dealing with an escape sequence (I assume).

But this is just my random guess at the solution to your problem…  
so… keep it ruby 🙂

This works, but that’s not the point. The fact is that  
puts ‘\c’ works inside a Ruby program, but does not work  
within irb.

Does anyone know whether this this a known limiation of irb, or a bug?

Thank you! I had overlooked your reply and have in the meantime  
already opened a bug report on the Ruby bug tracker (id 12868) ☹

This is a bug of irb. I fix this bug in ruby-trunk(Ruby-1.9).
