Support for VARBINARY Fields for Unicode

[palisadoes]

How should I configure graphene-sqlalchemy-filter to account for VARBINARY fields in a SQLAlchemy model?

I have no issues using graphene-sqlalchemy-filter filtering on INTEGER columns. With VARBINARY defined columns, I can filter using numeric only strings with these caveats.

1. Filtering with a "0" gives every value.
2. Filtering with an "AlphaNumeric" value or a a numeric value with a leading zero gives this error. The character referenced is the location of the first non-numeric character in the string. In this case the filter string was "75556b"

{
  "errors": [
    {
      "message": "Extra data: line 1 column 6 (char 5)"
    }
  ]
}

You can view my code here where I'm attempting to filter the PairXlate table on key (VARBINARY) and idx_pair_xlate_group (BIGINT).

What type of data is stored in VARBINARY? Can you give some examples of sqlalchemy queries you are interested in?
