http-equiv metas should trigger helpful upgrade messages

[jidanni]

When encountering

 <meta http-equiv="Content-Type" content="text/html; charset=utf-8">

print

 'These days one can just write <meta charset="utf-8">'

In fact tidy already prints

  line 8 column 2 - Warning: discarding unexpected <meta>

about the latter, if it finds both.

Also when encountering

 <meta http-equiv="Content-Language" content="zh-tw">

print

 'These days one can just write ...' etc.

@jidanni, hmmm, this has the whiff of an undefined feature request...

But when, where, what, and why, need to be clearly spelled out, specified, detailed, discussed, ...

Meantime closing this as too sketchy...

At a minimum, please provide feedback, input samples, config used, current output, and, more important, full expected output... to re-open... or open new issue(s)...

Look forward to further feedback, patches, or PR... thanks...

(To create samples just place the above meta lines into a HTML page.

The proposed output is like I gave except you can make it more formal sounding.)

@jidanni, your reply does not add anything...

To create samples just ...

If you have no interest in doing that, giving complete samples, that can be run through the W3C validator, and Tidy, who do you expect to do it for you?

The proposed output is like I gave ...

But what you gave is just not TRUE, in all cases, and the second case is INCOMPLETE anyway...

That is supply the when, what, why? And pointer to W3C RECS can help...

Yes I can assume this or that, but you, the proposer must make it clear, and not expect others to fill it out, by their guessing...

about the latter, if it finds both

Yes, but with experimentation I find Tidy discards the second in all cases. That does not seem right, in all cases...

So you have provided nothing new! No fleshed out, more complete, proposal, so this remains CLOSED... thanks...
