can't import utf-8 with BOM

[mlwang]

Ran into another issue just now: it seems UR doesn't understand plain text file with byte order mark (BOM). Import any text file in utf-8 with BOM and nothing is displayed in UR. Re-saving the file without the BOM (in an editor) and the file is displayed fine.

Could you please take a look into this? I've quite a few utf-8 text files (a necessity when working with Asian text), and saving them with BOM makes it easier for editors to identify the encoding of a file.
