Originally assigned to: @NghiaTranUIT on GitHub.

Proxyman version? (Ex. Proxyman 1.4.3)

3.1.0 (30100)

macOS Version? (Ex. mac 10.14)

12.2.1 (21D62)

Steps to reproduce

Load a URL that has a single quote in it. As an example https://example.com/api/v0.4/paymentmethod?$skip=0&$filter=currency%20eq%20'USD'&$top=25 (that was copied from the capture in Proxyman)
See URL loaded in Proxyman.
Right click and select "Copy cURL"
Paste into a terminal (I use iTerm)

Result:

curl 'https://example.com/api/v0.4/paymentmethod?$skip=0&$filter=currency%20eq%20'USD'&$top=25' \
-H 'Host: example.com' \
-H 'Connection: keep-alive' \
-H 'Accept: application/json' \
-H 'User-Agent: XXXX' \
-H 'Authorization: Bearer XXXX' \
-H 'Accept-Language: en-US,en;q=0.9' \
--proxy http://localhost:9090

Running the above will result in the URL being fetched without the single quotes. Copied URL as captured by Proxyman is https://example.com/api/v0.4/paymentmethod?$skip=0&$filter=currency%20eq%20USD&$top=25

Expected behavior

Single quotes should be escaped for the shell:

curl 'https://example.com/api/v0.4/paymentmethod?$skip=0&$filter=currency%20eq%20'\''USD'\''&$top=25' \
-H 'Host: example.com' \
-H 'Connection: keep-alive' \
-H 'Accept: application/json' \
-H 'User-Agent: XXXX' \
-H 'Authorization: Bearer XXXX' \
-H 'Accept-Language: en-US,en;q=0.9' \
--proxy http://localhost:9090

Thank you. Also wanted to say I really like Proxyman, very useful tool 👍

It's possible the software producing that query string should actually escape the single quote as %27 but I think the above should still work in any case.
