Passing a hidden field from an embed code as parameter breaks the value when the value contains a comma

I’m customizing a statement slide on my Typeform, using data from a DB and passed with PHP as hidden value using the parameters in the embed code.

I noticed that if my value contains a comma, typeform shows just the part before the comma.

For example, if I pass “This is the first, this is the second”, on Typeform I see just “This is the first”.

I tried to convert the comma into %2C, but no luck (I see all the statement, but I see “%2C” and not the comma.

There’s something I can do? Actually I’m removing the comma via PHP but it’s not the best solution for my needs. (I’ve to show stores addresses)
