Any plans to add this in the future? I would like to have this kinds of files open natively on Textastic.

Trying to open the file in UTF-16 crashed Textastic. Tried UTF-8 and UTF-32 and i see some text and stuff. Some of it readable.

First line says bplist00ß\

TextWrangler on the mac opens the file just fine.

Any plans to add this functionality in the future?

.strings files usually have localization in them and it would be nice to be able to open them.
