Path Issues; Validator Unable to Locate Files or Folders if Unwise Characters Present in Folder Name

[bendhouseart]

Recently was running the validator on a dataset as one does, but after renaming the dataset to better reflect the accompanying paper I began to run into issues w/ the validator not locating common files, subject folders, etc..

Path name is attached along with the output from running the validator.

Renaming the path to something more sensible seemed to ameliorate the issue, additionally it appears that OpenNeuro did its own version of sanitizing the errant path name after uploading. Should have the dataset published/snapshotted, but let me know if you would like me to send you a reviewer link or add you onto the dataset there in the immediate.

Bug can be reproduced by renaming a valid bids dataset to the folder name below.

This is almost certainly a problem with regular expressions, so I don't think this should affect the schema validator. Please add the schema label if it's still a problem.
