add tests about multibyte utf-8 characters

[dbu]

we should test #84 - some of it in https://github.com/phpcr/phpcr-api-tests/ rather than just here.

we can also check if #55 or #65 can be relaxed now, they where about encoding problems.

Currently it seems the jackrabbit adapter does not support emoticons like 😢. They fail at current function:

jackalope-jackrabbit/src/Jackalope/Transport/Jackrabbit/Client.php

Lines 1329 to 1331 in 7381adf

	$regex = '/[^\x{9}\x{a}\x{d}\x{20}-\x{D7FF}\x{E000}-\x{FFFD}]+/u';
	return (preg_match($regex, $string, $matches) === 0);

Seems like it has todo with the linked PR here in #55. Do you know anything about emoticon support in jackrabbit, do we need to add any encode / decode functions to support such a thing.

i did not look into this in a long time. jackalope-jackrabbit runs against the old-ish jackrabbit and we never took the effort to upgrade to oak. not sure if the latest jackrabbit builds would support it. afaik people did things like url-encode on their node names to handle this.

[alexander-schranz]

@dbu For the name we are doing also url-encode/decode. But for the value we are not doing this thing. But if I understand you correctly the regex just avoids a jackrabbit call which would error and output a nicer error message, so it could be that newer jackrabbit version would not fail so we could remove this regex?

[dbu]

oh sorry, i misread what this is about. yes you could try what happens with a newer version of jackrabbit. if it works, then we can add some logic to only check this if jackrabbit is too old, or relax the check if more things work.
