Answer 2

It appears that the text you provided consists of a single character: "ь". This character is from the Cyrillic script and is called "soft sign" or "yeru" in Russian. The soft sign doesn't have a specific meaning on its own but is used in the Russian language to modify the pronunciation of the preceding consonant.
