Re: -T changed behavior

Welcome to the Monastery.

[Please put code, data, program output, and similar text within <code>...</code> tags. This has a number of benefits: your posts will be easier to read; you won't need to escape special HTML characters (e.g. turn '<' into '<'); it provides a download facility so we can get a verbatim copy of your code.]

You can find the Perl deltas in the Miscellaneous section of perldoc. Looking in perl5220delta: Selected Bug Fixes, there's a reference to '-T' that may be what you're looking for. There's another in the Performance Enhancements section but that doesn't look relevant to me. If those don't help, try other deltas in the version range you specified.

You might also want to try:

$ file spk_pre_180208_180715_180419_bpo12_p.bsp
[download]

How does the output from that compare with what '-T' is telling you?

I don't have any of those Perl versions handy so I can't do any direct testing for you.

I think you might be right about that entry in perl5220delta. Just for reference, I think that the corresponding commit is `f13c8ddbf`, which references this P5P thread. Of course, we really need tothestars to show a SSCCE, then it'd even be possible to run a git blame to narrow it down to the exact commit. But using the above information, it might be something related to misdetection of UTF-8. tothestars: Note that -T is a heuristic test only, for example, the documentation has always said (emphasis mine): "The first block or so of the file is examined". If you want any kind of certainty, you should use a more reliable method - what's best here depends on what you're trying to achieve with this test.	[reply] [d/l]
