Revert "fix: convert invalid uri regex"

This reverts commit 0e935d1.

It fixed the crash of #70, but by always replacing special characters in
references by ":", so an external reference pointing to the "source
archive" "a%1.zip" would become "a:1.zip" while it should be
percent-encoded to "a%251.zip".
