This template trims matched pairs of leading and trailing single (') and double (") quotes and whitespace from a string. The string should be passed as the first unnamed parameter or using |1= or |s= if your string contains any = signs.
((trim quotes|1= Alex said "hello")) produces Alex said "hello" (since the quotes aren't at the beginning and end of the string)
((trim quotes|1=''zut alors!'')) produces zut alors! (the double-apostrophe that would otherwise display the phrase in italics is removed)
((trim quotes|1='''This place is not a place of honor''')) produces This place is not a place of honor (the triple-apostrophe that would otherwise display the phrase in boldface is removed)
((trim quotes|1="fish" and "chips")) produces fish" and "chips (the quotes at the beginning and end are removed, those in the middle are unaffected)
