There's something about this code I don't understand:

$fixtags = array( # french spaces, last one Guillemet-left # only if there is something before the space '/(.) (?=\?|:|;|!|%|\302\273)/' => '\1 \2', # french spaces, Guillemet-right '/(\302\253) /' => '\1 ', );

If I'm not mistaken, the sequence \302\273 is actually referring to a right guillemet (») and the second regular expression is referring to the left guillemet («), just based on the behaviour.

But what encoding is that? What does the \302 do? I grok regexes, but not php.

Also, what exactly is the (.) for? What situation is it trying to avoid?

Thanks, Steve
