How to find out the weird blank characters?
I have a text file downloaded from the web, I want to count the unique words used in the file, and a person's speaking length during conversation by counting the words between the opening and closing quotation marks which differ from the standard ASCII code. Also I found out the file contains some weird blank characters that are invisible from stdout which are the entry that has 118391 and the one has 6380 occurrence in the example.
It seems to me the file was processed with Mac PC by the single/double quotes I can guess, but I am not sure. Here is the output of my Ubuntu terminal:
Code:
tr -d '[:blank:]' < infile.txt | grep -o "." | sort | uniq -c | head
      4 ·
   1089 ‘
   1098 ’
  12146 “
  12147 ”
 118391 　
   6380 
  12237 about
     31 alot
    154 apple

1) How do I find out the invisible "blank/empty" characters in the file so that I can get rid of them in order to count the words?
2) How do I count the speaking duration of a person at conversations by the opening/closing double quotation pair? What I tried is:
Code:
grep "“.*”" infile.txt

This regex is too greedy that sometime combines adjacent dialogues into single one.
Thanks!

set_color

set_color(1)							       fish							      set_color(1)

NAME

       set_color - set_color - set the terminal color

set_color - set the terminal color
   Synopsis
       set_color [-v --version] [-h --help] [-b --background COLOR] [COLOR]

   Description
       Change the foreground and/or background color of the terminal. COLOR is one of black, red, green, brown, yellow, blue, magenta, purple,
       cyan, white and normal.

       o -b, --background Set the background color

       o -c, --print-colors Prints a list of all valid color names

       o -h, --help Display help message and exit

       o -o, --bold Set bold or extra bright mode

       o -u, --underline Set underlined mode

       o -v, --version Display version and exit

       Calling set_color normal will set the terminal color to whatever is the default color of the terminal.

       Some terminals use the --bold escape sequence to switch to a brighter color set. On such terminals, set_color white will result in a grey
       font color, while set_color --bold white will result in a white font color.

       Not all terminal emulators support all these features. This is not a bug in set_color but a missing feature in the terminal emulator.

       set_color uses the terminfo database to look up how to change terminal colors on whatever terminal is in use. Some systems have old and
       incomplete terminfo databases, and may lack color information for terminals that support it. Download and install the latest version of
       ncurses and recompile fish against it in order to fix this issue.
