#18 path name contain Chinese ideograph breaks

[Zhang Weiwu]

Sorry to lazy to write full report, as I am developing a solution for this at the moment, I keep this bug here for the record. In short, if a folder name contain ideograph, the folder, either using as a gallery or as an album, fail to display any images in it.

This issue is a bit complicated.

- there is no encoding convert in singapore, so only when filesystem encoding is the same as langauge charset that the webpage (with both filenames and UI) doesn't produce junk text.

I am doing:
- if there is no mbstring features, the system work as is, the old way.
- if there is mbstring feature,
1 adding configuration parameter default_encoding for encoding of filesystem encoding.
2 convert both language translation encoding (A) and file system encoding (B) to UTF-8 in the final page output.
so that always output page content in UTF-8
3 remove "default_charset" option in configuration to avoid confusion. It is not needed anyway because all languages define their charset.

Today on my local copy. I just did 1, 2.A. TODO: 2.B and 3
