      When a mongod is starting using wiredTiger and --directoryperdb, characters in the database name are exposed to WiredTiger and interperated as a part of the Data Source URI described at http://source.wiredtiger.com/1.6.5/data_sources.html. This means that, for example, the colon character : is seen as a separator between a table name and a column group name. Additionally WiredTiger will filter out the following characters from the name: {},:[]\\\"'
      This will occur in the function __wt_str_name_check
