Well, you sort of can, but it's a hideous hack and you really shouldn't. Because in nearly every scenario, someone editing a text file will care far more about finding the actual character than about finding the UTF-8 bytes.
I say "appears to become" rather than "becomes" because This is because it has taken the UTF-8 text of your file, and reinterpreted it as "ANSI" which is a terrible encoding name because it's completely wrongand should really be called "Windows"but that's a different question.
Digressions aside, here's why this will be helpful. In the "ANSI" really Windows encoding, each byte is a single character, and so now you're going to be able to search by individual bytes. Sort of. Because there is no character at the 0x81 point in Windows encoding: see for yourself. So why do I say that you really shouldn't do this? Errors should never be silently ignored, and having a 0x81 value in Windows text is an error. Stick to searching for real Unicode codepoints, and you'll be much better off.
Remember that in regular expressions, brackets represent "any of these characters".Win 10, SET NOTEPAD DEFAULT ENCODING to UTF-8
The docs further say, "See note about lower case [sic] letters," and the note about lowercase letters says "this will fall back on "a word character" if the "Match case" search option is off. Phew, that turned out to be a very long answer for what I said would be "very simple". I hope this helps you understand Unicode a bit better; if so, the hour I spent typing this up will have been worth it.

How to identify Non-unicode characters in a Text file
It says there are known issues. I've never ran into those. Sourcecode is available and one really should forge the code and redo some stuff. I recommend the use of free hex-editor "hxd" anyway for more than a quick view into the binary. Sign up to join this community. The best answers are voted up and rise to the top.

Thanks Razor2. All other spaces have a pink dot, this character is empty. I will research, but do you know what this means? It means it's not a space or a tab, and it's considered printable.

Net and its accuracy.When editing a text file in Windows it is sometimes necessary to embed special non-printable ASCII control characters into the text.
This is quite difficult in modern Windows versions. Windows does not allow any way to enter codes below code space into standard text fields. Notepad supports entering some of the character codes using ALT key codes. Number Lock must be turned on and you have to enter the numeric code on the numeric keypad it will not work using the regular number keys.
The symbol will be displayed in the editor and you can copy and paste it into other text files to embed the control code into them. Be warned that many Windows programs and text boxes may attempt to convert the character code into something else when you copy and paste it I believe it may have to do with Windows converting it to UNICODE.
Notepad even displayed a similar character to the one in DOS Edit but it still was as a different character not code 12 when I checked.

How do I check Non- Ascii characters inside a text file using C Sharp
When coding in Python I copy-pasted some code from the web and it appeared indented correctly. But running the code resulted in indentation errors, which I solved in the end by removing all "visible" spaces at line beginnings and inserting the same amount of spaces again. Is there a setting to fix this? Yes, it does. On newer versions you can use:. Double check your text with the Hex Editor Plug-in. In your case there may have been some control characters which have crept into your text.
Usually you'll look at the white-space, and it will say 32 32 32 32, or for Unicode 32 00 32 00 32 00 32 You may find the problem this way, providing there isn't masses of code. Yes, and unfortunately you cannot turn them off, or any other special characters. So if you want to read some obscure coding with text in it - you actually need to look elsewhere. I also looked at changing the coding, ASCII is not listed, and that would not make the mess invisible anyway.
