ArgumentError (invalid byte sequence in UTF-8)

[aussiDavid]

When sending a request that contains a non-UTF-8 character raises ArgumentError.

To recreate the issue:

1. Install apipie in a rails application
2. Start rails
3. Run this request in the browser http://localhost:3000/%B8

Partial Backtrace:

apipie-rails (0.5.19) lib/apipie/static_dispatcher.rb:12:in `gsub'
apipie-rails (0.5.19) lib/apipie/static_dispatcher.rb:12:in `match?'

It appears the issue is in attempting to apply a regex on a non-UTF-8 string in the static_dispatcher.rb file.
