URI#escape

is the wrong command to use.

Shellwords#shellescape

Should do fine. This isn't a Puma issue, this is your config issue.

See http://www.ruby-doc.org/stdlib-2.1.5/libdoc/shellwords/rdoc/Shellwords.html for more info.

Thanks momer. I didn't know Shellwords#shellescape.
But it occurred an URI::InvalidURIError like first code result.

URI#parse seems it cannot parse a shell-escaped uri.

[1] pry(main)> URI.parse Shellwords.shellescape('unix://space char/test.sock')
URI::InvalidURIError: bad URI(is not URI?): unix://space\ char/test.sock
