Open the file in Notepad. Click 'Save As...'. In the 'Encoding:' combo box you will see the current file format. Yes, I opened the file in notepad and selected the UTF-8 format and saved it.
You can view or change this default in the Tools : Options (for Windows & Linux) or Preferences (for Mac) dialog, in the General section. If you don't set a default encoding, files will be opened using UTF-8 (on Mac desktop, Linux desktop, and server) or the system's default encoding (on Windows).
To detect encoding of the strings you should use detect_str_enc() function. It is vectorized and accepts the character vector. Missing values will be skipped. All strings in R could be only in three encodings - UTF-8 , Latin1 and native .
There are a few options you can use: check the content-type to see if it includes a charset parameter which would indicate the encoding (e.g. Content-Type: text/plain; charset=utf-16 ); check if the uploaded data has a BOM (the first few bytes in the file, which would map to the unicode character U+FEFF - 2 bytes for ...
I realized, the answer is really simple: Just go to Edit => Find (Strg + F) and search for [^\x00-\x7F] + with enabled Regex field in the search bar.
