Is there a way to trim values, with the same implementation as .replace()?

[FonixAU]

I am trying to do some dynamic flattening, and the only issue I cant get around, is that there are some characters I am replacing, that may appear at the ends and inside the string, so I am not able to stop my macro from creating trailing underscores

eg:{{ row.replace("．",'_') .replace(".",'_') .replace(" : ",'_') .replace(":",'') .replace(",",'_') .replace("?",'') .replace("-", '_') .replace('/', '_') .replace('(','_') .replace(')','') .replace(' ', '_') .replace('___','_') .replace('__','_').upper() }}
