Hi

I can’t use string interpolation in irb,  
when using the “swiss german” keyboard layout and windows xp console.

When I try to enter this:

irb(main):001:0\> print " test #{}"

it’s turned into this:

irb(main):001:0\> #print "test  
irb(main):002:0\* {}

I guess this is a bug. If so where do I report it?

Thanks
