Based on rfc3986,  there are special characters that should not be used by themselves and should be encoded. The following are reserved and shouldn't be used without being encoded:

reserved    = gen-delims / sub-delims
gen-delims  = ":" / "/" / "?" / "#" / "[" / "]" / "@"
sub-delims  = "!" / "$" / "&" / "'" / "(" / ")"
                  / "*" / "+" / "," / ";" / "="

All of the below is unreserved and allowed in a URI:

unreserved = ALPHA / DIGIT / "-" / "." / "_" / "~"

Have the application team use the encoding structure based on the rfc398. For help with encoding this, this document can be used as a reference.
