Subject: assembling a string of characters?

hello,

how to create a string from variables containing numeric values of range 
0..255?

print "\32\32\32" # => '   '

#i tried the following:
a = 32
"\\#{a}"*3 # => '\32\32\32'

now i would like to let ruby process the result again to get the desired 
result '   '.

1) how to invoke string processing?
2) there must be an easier way to assemle characters to a string?
