Maybe something went wrong when pasting your code, because the following "hex dumper" shows me a \x20 from a line pasted:

perl -lne "printf qq([%s] => %02x\n), $_, ord $_ for split //"
mmu-miR-150
[m] => 6d
[m] => 6d
[u] => 75
[-] => 2d
[m] => 6d
[i] => 69
[R] => 52
[-] => 2d
[1] => 31
[5] => 35
[0] => 30
[ ] => 20
