>>15108166The best way to confirm this yourself is to deposit and then check the summary of a Pokemon that you've named, HOOPA.
Checking the Summary it will be fixed to Hoopa.
Now deposit something like HOOPE, it stays as HOOPE in the summary.
Then try any other real Pokemon all capitals, and it will be fixed as the game data matches it name.
Not only that. But Non Japanese players cannot use the in-game Japanese keyboard. This American here is asking for フーパ, Hoopa, and it gets translated on the GTS for Japanese players.
The names exist in the game data. We will see them as some type of event in the future.
