SOLVED: How to find: Blank Char / Invisible Character AND Hidde Char

[Debugger]

This document contains characters... (Current Encoding: 1250).


How to find/DETECT a strange character?
This is strange for me because it is a simple text in Polish, so the 1250 encoding is 100% correct.

To search for any character with PCRE regex not in code page 1250:

He finds nothing.
I tested in Notepad++ and EmEditor.

Any character with PCRE regex not in code page 1250.png

[Debugger]

Your screen presents a differently configured Emeditor interface, or a version other than the latest version of EmEditor (Pro version)

A strange symbol can also be something that can not be seen.

I have no idea why can not save text with the default encoding.
Which symbol, unicode, special character, it makes it impossible and how you save eg without UTF-8 you will get the name

Code: Select all

??

That's just the find toolbar (menu "View" - "Toolbars"...) - I use EmEditor Pro Version 18.6.91 x64.

If I want to save a file with special characters (as shown in the picture) as .txt file,
then "Save as Unicode (UTF-16LE with signature)" is automatically suggested to me...
The storage in this format allows me to open the text file without any problems and later on
saving without any further request.

[Debugger]

I understand. Filter Toolbar
but he still does not detect the strange char
I want to save as 1250 - for the Polish text. I do not need any UTF-16LE.
I also tried online tools to detect strange characters, but they also can not detect strange char.


Detects the Polish text, but does not detect strange characters.
[a-żA-Ż ?,:]

[tuska]

I understand. Filter Toolbar

No, I meant the "Find Toolbar"! -> Menu "View" - "Toolbars" - "Find Toolbar"

Did you paste the code in the field "Find" of the "Find Toolbar" and
- clicked on button "Use Regular Expressions" in the "Find Toolbar" and
- then clicked on "Find Next" in the "Find Toolbar"?
I then get the special characters marked as shown.

[Debugger]

But in my text there are no special characters you mentioned.

I have checked thousands of different Unicode, and still do not detect a strange or illegal symbol.
