URL parameter values with spaces are not mapping to Marketo properly

[Anonymous]

We have a few values within our url paramters that require a space in order to stay consistent with our existing values in Marketo/SFDC. For example, ?source=web&details=white+paper would normally come into Marketo as source = web and details = white paper. I just did a recent test and it is now coming into Marketo as source = web and details = white+paper which is not what we want.

I also tried doing ?source=web&details=white%20paper and ?source=web&details=white paper but both methods are not working.

Has anyone else had this issue? Is there anything I can do to the link to keep the space?

I believe "?source=web&details=white%20paper" should work. How is it appearing in Marketo?

It is giving me a Marketo value of white%20paper

Also. the link doesn't break in chrome (%20 is in tact) but if I use Mozille the link becomes ?souce=web&details=white paper
