Squid ACL does not block Arabic script, who faced?

Question

Squid

I will hide the domain (so as not to distribute)
ACL : www\.ala*****a\.net/ar/arab-and-world/syria/2014/09/02/-%D8%AF%D8%A7%D8 %B9%D8%B4-%D9%8A%D9%87%D8%AF%D8%AF%D9%88%D9%86-%D8%A8%D9%88%D8%AA%D9%8A%D9 %86-%D8%B7%D8%A7%D8%A6%D8%B1%D8%A7%D8%AA%D9%83-%D8%A7%D9%84%D8%B1%D9%88%D8 %B3%D9%8A%D8%A9-%D8%B3%D8%AA%D8%B5%D9%84-%D8%B9%D9%82%D8%B1-%D8%AF%D8%A7% D8%B1%D9%83\.html
URL : http://www.ala*****a.net/ar/arab-and-world/syria/2...
The url itself is Arabic, everything is in UTF 8 (Russian urls skip too)
In the log it says - TCP_IMS_HIT/200 16523 GET %URL%
UPD: By the way, Ukrainian also skips very often
