Minimal reproduction code and steps

Observe that the full argument string is being sent from the shell (as visible in debug mode)

However, when the URL is displayed in verbose mode, the URL is truncated at the first hash mark. (And the server logs confirm that the request URL is truncated).

Current result

The query string is truncated at the first hash character. …

Expected result

The full query string is sent to the server.

I think this is intended behaviour. See https://stackoverflow.com/questions/940905/can-i-read-the-hash-portion-of-the-url-on-my-server-side-application-php-ruby

You're right, this is mostly shopify being silly - they explicitly send a urlencoded # character in their queries to your service endpoint. https://shopify.dev/docs/apps/fulfillment/fulfillment-service-apps/manage-fulfillments#step-8-optional-enable-tracking-support

Their example URL: http://myapp.com/fetch_tracking_numbers.json?order_names[]=#1001.1&order_names[]=#1002.1&order_names[]=#1003.2&shop=testshop.myshopify.com&timestamp=1669900140

A question (not a bug, but a potential feature) is, would it be worth allowing httpie to support urlencoding illegal characters in cases such as these where we have to simulate requests that are being made that use the # character in the url?
