Re: how do i reset text coding?

[jimdam, vani]

. is this a text-mode (a.k.a. "TTY") frame or a GUI frame?
gui frame
  . what kind of "numbers" do you see? please show examples
file1 screen shot https://ibb.co/kBnGx7P
file2 screen shot https://ibb.co/HPxPrZH
  . what else is in file1 and file2 besides the Kannada text? what are
    the differences between file1 and file2?
file1 https://bpa.st/raw/5LLTY
file2 https://bpa.st/raw/ZOPXK
  . what happens if you create a file with _only_ the Kannada text?
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?
