Here's the output for the guava CaseFormat and for a new hand-coded function in Java.
The custom
convertFieldNameForBqhandles appending an underscore if the name starts with a digit. The only other difference I'm seeing from the rust results is that the rust lib removes leading and trailing underscores, which we don't do here. I also don't know that we have any actual field names that start or end with underscores, so this doesn't particularly matter.
