I guess the question is are you testing that the link text is a specific Chinese character? Or are you testing the link and it happens to be using a Chinese character? If you need to click the link and it doesn't matter that it is a Chinese character than you want to have some attribute on the link that never change when the language changes. For example <a href="some link here" qa-data='never changing attribute'>
报告</a> then I find the link using the CSS "a[qa-data='never changing attribute']". The link text can change but the qa-data will always be the same.
Now if you want to test that the link has the text 报告 then I would use a YAML file to change what you are looking for at run time. You write the test so it uses a variable for the text you are looking for. At run time you read in a YAML file with the actual text. This is probably how the developers write the website to use different language as well. You want to mimic this logic.
