I have translated Bengali phonetics into English. But after parsing, I got some trash characters, which I want to remove. My data frame looks like this.

```
col1        
utto্tor        
dokkho্shin     
muuns্si    

```

So I want to remove the trash character along with its previous and following character as well. For example: In the first row, I want to remove **্** - this character and also the character **o** and **t**, which is the adjacent of **্** (this) character.

My desired output is looks like the following-

```
col1            col2
utto্tor        uttor
dokkho্shin     dokkhhin
muuns্si        muuni

```

***P.S.*** I have got these kind of character by using *Avro parser* which looks like below:

```
reversed_text = avro.reverse("উত্তর")
print(reversed_text)

output: utto্tor

```

```
col0        col1
উত্তর       utto্tor
দক্ষিণ      dokkho্shin
মুন্সী         muuns্si

```
