Missing characters

### The problem

I don't know how long this problem has existed (there was no such problem in the past), with ESPHome 2023.11.6 when I create a new FW, it does not display the accented letters (even without an accent).

Example:
ESPHome code:
esphome:
name: eloszoba-erzekelok
friendly_name: Előszoba érzékelők

binary_sensor:
- platform: gpio
pin: GPIO35
name: "Bejárati ajtó"
device_class: door

Normally, I should receive such an entity identifier in HA: binary_sensor.eloszoba_erzekelok_bejarati_ajto
Instead I get: binary_sensor.elszoba_rzkelk_bjati_ajt

So the following accents are not converted to unaccented ones: á, é, í, ó, ő, ü, ű (these are also used in Hungarian words).

Maybe I'm wrong but it seems that UTF-8 encoding doesn't work if friendly_name: Előszoba érzékelők is entered under esphome:.
Neither in friendly_name nor in entity ID.

I want the entity id not to omit the accented characters, but to replace them with plain characters.
That is, let á=a, é=e, í=i, ó=o, ő=o, ü=u, ű=u.

Entity name: Bejárati ajtó
Currently I get this: binary_sensor.elszoba_rzkelk_bjati_ajt
This would be correct: binary_sensor.eloszoba_erzekelok_bejarati_ajto

Is it possible to correct this?
