how do i reset text coding?

[jindam, vani]

i am on debian testing. i have text "ಉಲ್ಲೇಖಗಳು" [kannada language 
alphabets] on both files: file1 & file2. for some reason it is showing 
text as series of numbers on file1 only. i have copied text from  file1 
and created another file [file3]. even file3 is showing same issue. if i 
hover over "U" [buffer coding system (multi-byte)] on all files [file1, 
file2, file3], it shows: utf-8-unix. i did ask on irc,  but i am lost. 
is there anyway to fix it without using commands? why this is not 
happening on file2?

regards,
jindam, vani

You didn't tell enough to answer those questions.

  . is this a text-mode (a.k.a. "TTY") frame or a GUI frame?
  . what kind of "numbers" do you see? please show examples
  . what else is in file1 and file2 besides the Kannada text? what are
    the differences between file1 and file2?
  . what happens if you create a file with _only_ the Kannada text?
  . what is the major mode Emacs uses for each of the files?

file3 kannada text only opens fine https://ibb.co/fVRBVD3
  . what is the major mode Emacs uses for each of the files?
C-hv shows:
 major-mode is a variable defined in ‘C source code’.

Its value is ‘text-mode’
Original value was ‘fundamental-mode’
Local in buffer wiki.txt; global value is fundamental-mode

Symbol for current buffer’s major mode.
The default value (normally ‘fundamental-mode’) affects new buffers.
A value of nil means to use the current buffer’s major mode, provided
it is not marked as "special".

  Automatically becomes buffer-local when set.
  You can customize this variable.

important: clicking customize, operate on all settings in 
this buffer: revert - reset settings:: resolved the issue?

On your first screenshot, the mode line shows ‘=’ instead of a ‘U’.
(info "(emacs) Mode Line") explains:

    ‘=’ means no conversion
    whatsoever, and is usually used for files containing non-textual data.

so that’s your issue: somehow, for that buffer, encoding is not set
correctly. (I don’t know why and where to look, so I will leave it to
others to help you diagnose it.)

Yes, exactly.

The screenshots don't show the entire text, and the text itself wasn't
posted here _as_text_, so it's hard to say.  But in any case, you can
do

  C-x RET r utf-8 RET

and Emacs will revisit the file with UTF-8 encoding.

Thanks.  I've downloaded the two files, and "emacs -Q" on my system
has no problems displaying both correctly.

Did you try visiting these files in "emacs -Q"?  Does the problem
still exist with "emacs -Q"?  If the problem exists with "emacs -Q" as
well, then what does Emacs show if you type "C-h C" (note: capital C)?

My guess is that there's a NUL byte in the file.

I use (setq inhibit-null-byte-detection t) in my ~/.emacs because I've
been bitten by those NUL bytes too many times.

In the files whose URLs were posted there're no null bytes.
