WireCache Unable to encode array data for cache..

[Can]

Hey folks,

just got an "Unable to encode array data for cache.." error from WireCache.

Had an ´ (acute accent) in a page title, after changing to ' (single quote)  everything worked again.

I have to say, that the acute accent didn't looked good anyway, got this weird black thing^^

The only thing I tried so far, was changing line 318 of WireCache.php to

$data = json_encode($data, JSON_PRETTY_PRINT | JSON_UNESCAPED_UNICODE | JSON_UNESCAPED_SLASHES); 

couldn't recognize any difference..

So am I better off changing those (don't know if there are more..) or what else can I do?

You could escape the values with 'htmlentities' — either manually or automatically via custom TextFormatter.

Edit: Or it's possibly something else; I've just $cache->saved an array with string with acute in it and had no problems.

Right, haha, that's why I waited with posting this question. Just forgot about additional thought I head...anyway after trying text formatter which didn't made the trick I narrowed it down to a custom character limiting function in my template.

After trying around I got it working by changing substr() to mb_substr() =)

Thanks Adam!

No problem.
