Redirect to external company website with ids

Hi
At the beginning of the survey, respondent will enter an id, I need to redirect the respondent to an external website after completion of the survey using that id as discussed here (https://www.qualtrics.com/support/survey-platform/common-use-cases-rc/panel-company-integration/#RecordingIdentifyingFields)
The problem is the id can be alphanumeric and will contain asterisks, which must be supported by the Qualtrics platform. Does Qualtrics support asterisks as input please?
Thank you in advance.
