I have an Excel file with some text. I have saved it as CSV file and read into R using `readr::read_csv2()`. But I cannot figure out how to get rid of the weird characters below:

```
[131] "W<U+008A>rmflasche <e3>Hug<d2>\r \r"                                             
[132] "Held f<U+009F>r einen Tag <d0> Aufblasbare Superhelden-Ausr<U+009F>stung \r"     
[133] "Metallic Tattoos & Haarkrone <d0> Fashion Set\r"                             

```

I tried to use `iconv` but I have no clue in which encoding the files was saved in the first place.

EDIT: I am adding the first lines of the csv file:

```
name;product_details
Geschenkset Cupcake Dekoration ;"Erh�ltlich in vier Varianten: Cupcake Geschenkset � Weihnachtsglitzer"

```
