PHP + preg + international chars problem

[yaba]

So are you saying I should "rebuild" every word I get off the DB to UTF8?

That seems a lot of processing :/

Even if I did that, how do I replace say 'α' with $alpha dynamically?

I'm just using that to create the character for the sake of example; try it as you normally would without extra processing. Also, the above code is not block/language/chart specific. They're basically Unicode classes, just like[tt] \b[/tt], [tt] \w[/tt], and[tt] \s[/tt].

Right, roger that :)

Could you elaborate a bit on the pattern you used please?

I don't think I've encountered before \p, for example. And those '?<=' and '?=.' bits you used... And correct if I'm worng, the \1 is what is captured by the first set of parentheses, right? I.e. (?<=\p{Z})

I don't quite get it, too advanced for me.

Any place I could check these out with examples etc? Couldn't find anything... Or some feedback? Thanks! ;)

[tt]\p{[i]property[/i]} [/tt]matches Unicode characters that have the property, whereas [tt]\P{[i]property[/i]} [/tt]matches Unicode characters that [u]do not[/u] have the property. (This is a common syntax for specifying "match" and "don't match"; compare to[tt] \s [/tt]and[tt] \S[/tt],[tt] \w [/tt]and[tt] \W[/tt].) The "Z" property is for "Separators," which "mark the boundaries between units of text." The[tt] (?<=...) [/tt] and[tt] (?=...) [/tt] are lookarounds, specifically, a positive lookbehind and a positive lookahead. They [i]look[/i]--they don't match. You can find more information on these from the links in my signature.

Therefore, the pattern results in:

[code]
/
(?<=\p{Z}) ### Make sure the next character is preceded by a separator.
(' . $alpha . ') ### Match the charaacter.
(?=.) ### Make sure the character is followed by another character, e.g., match "an" but not "a".
/xu
[/code]

If your server does not support unicode completely, here you can test the server's response and find out some tricks accordingly:
