Feature description

Please add Esperanto layout. It should likely be based on QWERTY English.

Why do you want this feature?

Because I write in Esperanto.

@flashymittens Is the Gboard layout ok?

Z Ĉ C V B N M

@tenextractor Looks fine to me. Should probably have ₷ (U+20B7; spesmilo sign) somewhere too, maybe long tap S or directly after M. It is a historical currency, not really in use nowadays, but, for example, it can be used in Esperanto stories (not exactly widespread, but I do that).

Wait, I forgot Ĥ and ĥ… cough Can we have one one after Z or M?

[tenextractor]

@flashymittens Ĥ comes after M, see the linked pull request

[flashymittens]

@tenextractor Ah, I see. Thank you :)
