Which version of python do you use?

[kixiro]

python 2.7.12

[SergeyPirogov]

try to user it like

s(by.xpath("//button[contains(.,u'Объекты')]"))

[kixiro]

Object will not be found

s(by.xpath("//button[contains(.,u'Объекты')]"))

It's work:

s(by.xpath("//button[contains(.,'Объекты')]"))

but object is not found, get UnicodeEncodeError
I resolved it this way:
