Expected behaviour:

If using tvdb_lookup to look-up a TV show with a localized name, it should be able to find it. Either automagically, or by specifying the language to search for.

Actual behaviour:

If using tvdb_lookup to look-up a TV show with its non-English name, it plainly fails.
It currently searches for English-name only.

Steps to reproduce:

• Step 1: Search for 'Tegenlicht' (=Dutch) -> fails to find
• Step 2: Search for 'Backlight' -> that works, but we don't have that name...
