Automatically replace erroneous curly quotes with straight quotes in shortcodes

[mauteri]

A common error among users I found is that some shortcodes they include in posts contain curly quotes rather than straight quotes for attributes.

An example of this that I just received this weekend from work:
[ione_social_wall id="544aa6d44b76c”]

As you can see, the second quote is a curly quote and can be easily missed if you don't look at it carefully.

I've included a diff for this. I placed the code in formatting.php in wptexturize. If there's a better place, let me know and I'll supply another diff.

Adds a str_replace in wptexturize to replace curly quotes with straight quotes in shortcodes

I think the replacement may need to be a little cleverer if it's going to be done there. Consider something like

[song title='Don’t leave me this way']
----------------^ = curly

which would end up as:

[song title='Don't leave me this way']

Made this one a bit smarter with a bail feature if it breaks the shortcode.

Thanks for the feedback.

I've provided a new diff (30856.1.diff) to cover the example you provided. I also put in a bail feature for situations like

[song title='Don’t leave peoples’ shortcodes this way']
--------------------------------^ = script will think curly space is end of attribute value and don't want that

In the rare cases above, the script will just bail and not try to clean up curly quotes. Let me know your thoughts and if you think something like this would work here.
