When creating a Module, what optional string can be used to indicate a space in the arguments field?

Using "%20" as an optional string in the arguments field to indicate a space is based on standard URL encoding practices. In URLs, spaces cannot be represented directly and must be encoded in a way that the web browsers can interpret correctly. The encoding for a space is specifically "%20", which is widely recognized in web standards.

When creating a Module in ServiceNow, utilizing "%20" effectively allows you to pass arguments that include spaces in a way that the system can process without errors. This consideration is crucial for ensuring that the Module operates correctly when arguments are parsed.

The other options do not meet the standards for encoding spaces in URLs, which is why they would not work in this context. Understanding the proper method of handling spaces through URL encoding is important for Application Developers working with ServiceNow.
