Hello,
Due to the incorrect setting of parameters in "languages and regional standards", the Cyrillic alphabet in the txt files was displayed as "hieroglyphs". By changing the parameters, I was able to return all files to the normal state, except for one (with which I worked and with which I experimented most, trying to return to the original form): it now has question marks instead of "hieroglyphs".
Tell me, please, is it possible to do something with it, or not? Thanks in advance!
