Title: Illegal Unicode escape sequence near index 52

The parser reports an error on at least the latest version of simpleCart.min.js library. It appears that the offending line is:
Illegal Unicode escape sequence near index 52
[^._0-9A-Za-z\xb7\xc0\xd6\xd8-\xf6\xf8-\u037d\u37f-\u1fff\u200c-\u200d\u203f\u2040\u2070-\u218f]

The same error is reported with the unminified version.
