Migrated from a really old Unirest version (1.4.10).
On that version, it escaped the spaces as %20, but now it doesn't so it seems like a regression.

Exception given:
Caused by: java.net.URISyntaxException: Illegal character in path at index 50: http://192.168.1.13:8000/v1/archivo/demo/expresion interes.pdf

To reproduce
GetRequest request = Unirest.get(any given url with a space);

Expected behavior
The url should be encoded to
http://192.168.1.13:8000/v1/archivo/demo/expresion%20interes.pdf

Environmental Data:

• Java 1.8.0_221b-11
• Unirest Version [3.1.04]
