Minified js file has unicode symbols like A-Za-zÀ-ÖØ-öø-ʸ̀֐ࠀ῿‎Ⰰ-﬜︀﹯﻽ which is breaking code

Question

A third party minified js file that I am using for my project has unicode symbols like "A-Za-zÀ-ÖØ-öø-ʸ̀-Öà €-῿‎Ⰰ-﬜︀-﹯﻽-ï¿¿" which is breaking my code. But when i replace them with their equivalent unicode characters like: 'A-Za-z\u00C0-\u00D6\u00D8-\u00F6\u00F8-\u02B8\u0300-\u0590\u0800-\u1FFF' + '\u200E\u2C00-\uFB1C\uFE00-\uFE6F\uFEFD-\uFFFF'; in the minified file itself, my code is working fine. But the problem arises when i try to check-in my code in my jira using putty command submit_files.pl, the sparta validator runs and gives a failure. How can i make that the validator pass? Is there any other way to deal with these unicode symbols?
