Created Issue: Unicode Issues [19423]

I used a older version of AjaxMin and when I minify the file Unicode characters are encoded properly

For example Bokade besök will be converted to Bokade bes\u00f6k

But with the latest update it doesn’t work. Following is the command I ran

```
ajaxmin "C:\Users\jeyakumaran_m\Documents\Rahmqvist\Source\JQueryMobile\lng\LANG.js" -o "C:\Users\jeyakumaran_m\Documents\Rahmqvist\Source\JQueryMobile\lng\LANG.min.js" -clobber
```

I even tried this

```
ajaxmin "C:\Users\jeyakumaran_m\Documents\Rahmqvist\Source\JQueryMobile\lng\LANG.js" -o "C:\Users\jeyakumaran_m\Documents\Rahmqvist\Source\JQueryMobile\lng\LANG.min.js" -clobber -enc:in utf-8 -enc:out utf-8
```

But no luck. Has anyone had the same problem??
