Let me repeat the question: I get some data from a foreign Perl module (let's say a file parser), and that module doesn't document what it returns.

But other parts of the code have to deal with text strings (for example because they query unicode properties).

What should I do? I only need to know that once, at write/debug time.

My current approach is to try to get some data with high codepoints (outside latin-1 range) out of the foreign module, and check with Devel::Peek or utf8::is_utf8 if that stupid flag is that.

Is there a better, more reliable approach? And is that really an abuse?
