We've identified all the characters for the second language used in the series and have created a chart for that language as well. Like the first language, its just a simple substitution cipher.

Added chart for 2nd Language: http://www.pocketmonsters.net/Anime_Language

Sushi found a very long usage of the language in BW33 which appears to be Professor Icarus's notes. Posted a couple links to some of the more interesting ones we've recently added to the notes section of the episode guide.

A Couple of Very Interesting Notes Added to Database:
Professor Icarus Notes: http://www.pocketmonsters.net/episodes/1259#Edits-edit1471
BW63 still using TSUTAZYA: http://www.pocketmonsters.net/episodes/1330#Edits
BW004 Character Urara: http://www.pocketmonsters.net/characters/Urara_Isshu

Added a couple more big edits to the database. A fourth language seems to have debuted in BW66 but have yet to be able to decipher anything positively from it.

BW64 - Laptop Screen - http://www.pocketmonsters.net/episodes/1335#Edits-edit1548

Just a note, I'm not posting all the links to all the language edits we've added in the thread. The update log keeps track of that. Just posting some interesting ones we've discovered here.

In the Movie 13 Ending, you will find a few instances of Anime Language too.

On the professor's newspaper:

Title of the newspaper: CD EFGHI
Article title: DEFGHIBC D
The letters visible in the newspaper half way down: JKLMNOP

It seems the TV he's watching has some anime language too.

BW69 had quite a few interesting notes that are anime language related. The QR Code Reader had quite a few fun easter eggs to figure out. I was more than surprised that the QR code actually worked. They should have made it link to the official website and Satoshi's bio. That would have been really cool.

BW69 Notes: http://www.pocketmonsters.net/episodes/1346#Edits

I tried to decipher some of the ones from the imageboards
So, here's what I have for now
This one: http://www.pocketmonsters.net/images/ib/64/13238864370088.jpg says
UVWXYZ
and this one: http://www.pocketmonsters.net/images/ib/64/13238864630070.jpg
says SOMULIE for the sign on the top and STJKNOP
VWXYZPOKEMON for the sign on the side

We generally don't add the alphabet ones to the episode guide because other than helping us initially figure out how to decipher the languages, its not really that interesting. We generally only add ones that have some kind of meaning. SOMULIE though is probably a misspelling of sommelier. We haven't gone back yet and indexed all the older BW episodes like BW19 which that screenshot is from but we have been keeping up with the latest BW episodes.

BW74 http://www.pocketmonsters.net/episodes/1357#Edits has quite a few interesting ones, especially the way they spell DONNAMAITE .

Thought that I would specifically point out these 2 really interesting language edits from BW83. We do add the language edits for every episode as they air though, so check previous episodes in the episode guide for other cool tidbits not specifically mentioned in this thread.

The first from BW83 is the side elevation of the Tesseed Laboratories which is shown on the screen. The second is the map of Tachiwaki City which is actually based on London, England as it specifically states the name of the river is the Thames.
