URLs with & ? and other special characters

[Skip]

I am implementing a new system where some of the key fields like productId,
partyId, etc have special characters in them.  When constructing a URL, for
instance EditInventoryItem?productId= and the productId contains one of
these special characters, I expected OfbizUrl to fix it form me.

for instance, findParty?partyId=ANDER&COTCH should be transformed to
findParty?partyId=ANDER%26COTCH

Is there ofbiz code to handle this?

Thanks in advance
