Signs instead of unicode

I installed Piwik on windows server 2008 r2 on iis 7.5, my piwik version is 2.12.1
I started to tracking some sites and it works perferct. a few days ago i added a new site to track and then i started to deal with a strange problem, with the new site only, some of the data is saved as “xx_x_xxx_xx” instead of unicode (hebrew). i noticed that there are some specific characters that the piwik does not recognize and therefore the entire data gets lost.

** all my tracking site are hebrew **
i tried to replace the font - as showen here:

i tried to change the collaction in the db to “utf8_unicode_ci” .

i tried to create a new site with form and input and the problem occuars in this site too

the code look like this:

i added a photo from the “piwik_log_action” that shows the problem.

the red rectangels are the problem, the green rectangles are ok.


thanks in advance,


Hi there

try with latest Piwik RC version: I would like to test early beta and RC releases, how do I enable automatic updates to use these development versions? - Analytics Platform - Matomo

if you still have a problem with new data (ie. the Piwik UI shows wrong data) please create a bug report then: Issues · matomo-org/piwik · GitHub
