@ManuelRühl , let me explain 'why'. I don't want to give the impression that it just works, the fact is it works as expected.
Explanation : your string is men's wear. In set analysis, if you use literal search, you include the string within single quotes. That means, it would look something like : 'men's wear' , but then qlik engine gets confused with the closing single quote and the string part apostrophe, so we have to use an escape sequence. There are many options for escape characters here but we are using the single quote. That is, when I write 'men''s wear', then the first (red) single quote is escape sequence; telling qlik engine to not consider the following (blue) single quote as special character to close the string but treat as a part of the string.
