R : Strange output from read_tsv(), 0 rows and 21467349 columns

Question

Does anyone know what type of charachter is this? I'm tryin to import this file in my R Session. The columns are tab separated (actually it looks to me that some are separated with 1 tab and others with 2 tabs) but when i open this plain text file in my editor it shows these "up arrows".

here a portion of the file:

the file is 184.686 kB

my code in a new started R session is:

to fit a complete line:
  * Increase it by setting `Sys.setenv("VROOM_CONNECTION_SIZE")`

# Sys.setenv("VROOM_CONNECTION_SIZE" = 180000000) still generates error so i go up with

i Use `spec()` to retrieve the full column specification for this data.
i Specify the column types or set `show_col_types = FALSE` to quiet this message.

#runs too long without giving any output and i stopped my R Session

After the file was wrongly "imported" i noticed that my R Session was using 16GB of memory:

Status of RStudio after the wrong import. System is using 16GB of memory

i am new to RStudio and R. I used read_tsv() because i thought the file was tab separated. I don't know if this problem (hence it says there are 0 rows) is due to the "up arrow" or the tab delimiter. I will be pleased if someone can give me an in depth overview of what's happening, and why the import was not succesfull. I would also like to know why my R session is taking up so much memory.

EDIT: it seems to me that columns are tab separated and rows are "up-arrow" separated. I say this, because the file on my macbook (textedit) looks like this: on mac: enter image description here

on windows: start of the file: beginning of file on windows end of file: end of file on windows

EDIT: using the UTF-8 Tool to identify the "up-arrow" charachter as mentioned in the comments result in this: UTF-8 Tool output Thank you in advance !
