Note:I'm editing the first message when a next user says what keyboard uses
In case you don't know,QWERTY is the most used keyboard,maybe some keyboards are QWERTZ or AZERTY or another layouts maybe
QWERTY ENG(US intl.)
JCUKEN RUS and UKR
YCUK[YE]N*
https://en.wikipedia.org/wiki/JCUKEN
JCUKEN , not ycukyen
y is used for bI letter
y is for "i kratke"<-how is the name?,for the "drak znak and I" maybe is "y"or something else and why "e" and not "ye" if russian shaped E has "ye" sound(je in IPA) and russian curved E but flipped has "e" sound
I kratka is J in more accurate transliterations (transl. Jabloko / official transl. Yabloko - apple) . "drak znak and i" doesnt even exist and i guess you meant Yeru(bI, jery actually) letter (Byvshyj / Byvshyy - ex- anyone). E as "ye" is only transliterated as word initial E (Jevropa / Yevropa - europe but Belyj / Belyy - white). "Curved flipped E" is only used at start of word (Elektrik - electrician)
Longer example :
Official : syesh zhe yeshche etikh myagkikh frantsuzskikh bulok, da vypey chayu
Accurate : sjesh z*e jes*c*eo etih m'agkih francuzskih buloc*ek da vypej c*aju
(* is used at place of hacek)
yeru/yery is the name of "bI"?
thanks for the help
