PHP generated two-dimensional code Chinese garbled how to do

Recently done a scan two-dimensional code to get a vcard project, encountered a problem, a part of the generated two-dimensional code, using the Android phone after scanning the Chinese name of the vcard is garbled, after the discovery, this part of the vcard org this type has no content, Immediately judged no content to add a fixed string, so garbled problem can be solved. This solution is a curve to save the nation, do not know how to solve the garbled problem, who get the method please leave a message, thank you.
