Re: [PHP] Cleaning pasted Word text

[a . h . s . boy]

Errr...I'm not sure how this is applicable to my situation. I'm concerned, above all, with converting

curly double quotes
curly single quotes
em and en dashes
inverted exclamation points
inverted question marks
ellipses
non-breaking spaces
registered trademark symbols
bullets
left and right guillemets

Many of these characters do not exist in the ISO Latin 1 character set, but can nonetheless be inserted by a browser which defaults to MacRoman or Windows Latin 1 (1252) character sets.

The big questions, I suppose, are:

1) What character/ASCII code does PHP interpret “ (left curly quote) as, when pasted into a form?
2) Does it interpret it the same way pasted in on a Mac as on a Windows box?
3) What influence does the page charset meta tag have on such a submission?
4) What influence does the form ACCEPT-CHARSET parameter have?
5) What influence does the browser encoding setting have on such submissions?
and finally,
6) If all of these factors can influence the final interpretation of a character, what's the best way to approach handling all possible combinations?

All of this would be soooo much easier if I'd just get my hands on a Windows box for testing. Guess I'll have to do that. I'm just a bit surprised that no one seems to have tackled this problem already...it can't be that uncommon.

Then again, I've seen any number of CMS-driven web sites that obviously haven't this sort of conversion, including large news corporation sites. And given the paucity of Mac-friendly programming on the web, it's not too surprising that so few sites attempt to accommodate Mac users. (Testing for Mac compatibility tends to be on par with testing for Netscape 3.0 compatibility...not usually a very high priority, despite IE 5 for the Mac supposedly being more standards-compliant than the Windows version.)

cannot remember I why put in two functions ... but anyhow have fun you
will probably not the the implode / explode either

Look at http://www.w3.org/TR/REC-html40/charset.html
and see if that
helps you. Below is a paragraph I pulled from it.

The document character set, however, does not
suffice to allow user
agents to correctly interpret HTML documents as they
are typically
exchanged -- encoded as a sequence of bytes in a
file or during a
network transmission. User agents must also know the
specific character
encoding that was used to transform the document
character stream into a
byte stream.
