When using xbps-fetch, the tilde (~) character is being url encoded into %7e. This is causing at least one xbps srcpkg to fail when downloading its distfiles .

For example, the following fails to find the udptunnel distfile (note the tilde character in the path)...

$ xbps-fetch -v 'http://www.cs.columbia.edu/~lennox/udptunnel/udptunnel-1.1.tar.gz'

Examining the TTY output, I can see that the tilde is being url encoded...

requesting http://www.cs.columbia.edu/%7elennox/udptunnel/udptunnel-1.1.tar.gz

Using curl to download this file works fine.
