I've been plagued with the same problem. Usually those posting are mac users.

I think it might have something to do with smart quotes but haven't been able to track it down.

Upgrade to 1.9.2 and all that will gon away. if you need help jut go to the forum me, sorry I'm drunk today!

Excellent, thanks!

ok, I've upgraded and the problem still persists.

an apostrophe shows up as '’'

Is this a "smart quotes" problem?

Example:

Ok, it's a 'Closing Single Quote Mark' that's causing the problem. I can reproduce it by putting one in a comment then submitting.

I'm looking into the texturize plugin code.

I have a strong feeling your problem is caused by a difference in charset in the mySQL database on the one hand and the blog (or the input) on the other.

Perhaps [url=http://manual.b2evolution.net/Charset_handling]this topic in the manual about charset[/url] helps you on the way.

But there are also known problems with the difference between a 'neutral' apostrophe and a closing single quote an the mac user (or even linux) might send the wrong character. Furthermore there might be problems when people copy / paste texts from Word.

Perhaps you can find out how the database stored the last comment from your link (the one with the errors).

Good luck

Thank you for all the good leads! mySQL char-sets never occurred to me. I'll track these down and return with my results.

I also wonder if users aren't cutting+pasting from word to use it as a spell checker.

This appears to be people cutting + pasting from word. The neutral apostrophe is repalced with a curly apostrophe.

Where would I modify the code to handle this errant character?

This is an educated guess:
edit ../blogs/plugins/_texturize.plugin.php.
Add after:

$curl = str_replace('---', '—', $curl);
$curl = str_replace('--', '–', $curl);
$curl = str_replace("...", '…', $curl);
$curl = str_replace('``', '“', $curl);

this line:

$curl = str_replace("’", '& #39;', $curl);

without the space between & and #. Look at the code in the file for details.

Good luck.

That worked perfectly for posts. Now, is there a similar function for comments or can I apply texturize to comments?

I checked my server the mysql character set appears to be latin1. Perhaps this is the problem as was suggested before. I believe it's the MySQL default, which seems odd.

Server characterset:    latin1
Db     characterset:    latin1
Client characterset:    latin1
Conn.  characterset:    latin1
