#203 black hdr image for non ascii chars in path if using auto align

[Gust Fried Wert Hegel]

Steps to reproduce:
- put the source images in a folder location where the path contains non ascii characters (e.g. german umlauts)
- convert the images to an hdr image using luminance hdr (applies to both the wizard as well as batch hdr)
- be sure to check "auto align" - otherwise it works fine
- the resulting hdr image is completely black (or grey, or white depending if tonemapping is applied)

See the attached hdr image which resulted from these steps.
Happens if using either JPG or RAW as source.

Environment: Windows 7 x64, Luminance HDR 2.4.0
Workaround: don't store images in paths containing non ascii characters

The same happens for me on Ubuntu 14.04 x64 when using images with underscore... i suppose its connected...

Thanks for Workaround!
