Expand character support in serve URL path (spaces and special characters)

[yilin-ang]

I am currently using go-pmtiles serve to host a directory of PMTiles files. Many of the files originate from external sources and contain spaces and specific symbols (e.g., forward slash) in their filenames. I have considered and find that it is not feasible to limit control and limit the file names to exclude spaces and forward slashes.

Is it possible to expand the character support to allow this?

The name constraints now are based on S3 safe characters: https://docs.aws.amazon.com/AmazonS3/latest/userguide/object-keys.html

to ensure the behavior is the same across local files and cloud storage. Is your directory local or on a cloud storage bucket?

If we enable slashes we need to add in checks for path traversal attacks, etc.

My directory is on a mounted storage bucket, hence it works similar to a local directory. I also have sub folders and go-pmtiles is working well in serving tiles within sub folders when I pass in the path.

I might still be able to exclude forward slashes from the PMTiles file names. However, spaces are pretty common and it will be great if spaces within file names could be supported.
