unicode alternative of multiple-argument pipe backward `↤*` does not work

[JayXon]

docs says ↤* is an alternative to <*|

ascii works

print <*| [1,2]

unicode alternative gives parser error

print ↤* [1,2]

CoconutParseError: parsing failed (line 1)
  print ↤* [1,2]
  \~~~~~~^

pipe forward works fine

Fixed as of coconut-develop>=3.0.4-post_dev17 (pip install -U coconut-develop>=3.0.4-post_dev17 to get the fix).
