Hi everyone, sorry for bad English. It's Ruby code.

s = "???????"

`touch #{s}`
`cat #{s}`
`cat < #{s}`

Can anybody tell why it's code fails? With

sh: cannot open ???????: No such file

But thic code works fine

s = "????????" 
`touch #{s}` 
`cat #{s}` 
`cat < #{s}` 

Problem is only when Russian symbol '?' in the word and with symobol '<'
