EncryptPad on snap doesn't write accents

[cfgnunes]

The EncryptPad 0.5.0.2 Beta on Ubuntu (installed via Snap) doesn’t permit input accent characters, such as: áàâãéêíóôõú.

When I normally write in all the rest of the programs, if I hit ' and e, I see é.

However, in EncryptPad app it appears the e without the tilde.

Same happens for all the composite letters. Note that this doesn't seem to be an "unicode" problem... if I hit "ñ" (I have a separate key in the keyboard for it), it appears ok.
