Concat substitutes &para in a string with a paragraph sign

Hi Xano team,

if I use concat to build a string that includes &para like a URL 'test.com/?param1=test&param2=test', &para is substituted with a paragraph sign, see screenshots below.

This is not just a frontend/presentation glitch in xano, but the string output that I return in an endpoint contains the paragraph sign. This is obviously a problem as I cannot construct a URL with these parameters.

Thanks Timo
