Some GDB formats use URI1 connection strings, which require URL2 encoding when special characters are used. Special characters include the comma (,), colon (:), slash mark (/), left bracket ([), right bracket (]), quotation mark ("), and so on. The URI specification lists some reserved characters that also must be URL encoded.
The following table identifies the URI reserved characters:
