[Zope] single quote in structured text

I am writing a section in a matlab guide on strings, using structured text. strings in matlab must be indicated by single quotes, as in x = 'My name', not x = "My name" I need to tell the structured text renderer to display the single quote. I have tried such shenanigans as ''file1a.dat'', 'file1b.dat', "'file2.dat'". The last one preserves the single quotes but also displays the double quotes, which doesn't really work either. Any suggestions? I can always fall back on the :: code environment.... Thanks, John Hunter
