Encoding problem

[alinusss]

While running zwaad with pineforest algorithm, if I put in the answer line the letter in russian encoding, then remove it with Backspace, then put the correct english letter, got error and process interruption.

the command is

zwaad --answers snad4_ans_AV.txt --anomalies snad4_anom_AV.txt --oid sid_snad4_r_100.dat --feature feature_snad4_r_100.dat --feature-names feature_snad4_r_100.name --budget 40 --random_seed 42 pineforest

then I got
Is 601210400015694 anomaly? [y/N]:
type russian letter, erase it, change encoding by "alt+shift" and got

the same thing appears, when I change the encoding through clicking on the language sign in the tray

if I type a russian letter, then erase it with Backspace and also erase the space, which is after : and type english letter, I don't get any error and continue normally
