Description of problem:
If the password of any CFME user contains an accent character e.g. from French or Czech (š, č, ř, ...), user is not able to login, no message is given by UI, nothing is captured in evm.log, api.log, production.log, audit.log or automation.log (even on debug level).
Same behavior we can observe, if the accent character is used in wrong password - no message about invalid password in GUI, no record in the logs. Only infinite loading spinning wheel animation, sometimes the page just refreshes.

From the web browser debug it seems that the password sending is blocked on browser level
