C# string special symbols

I used a regex to determine whether the string was made up of only letters and numbers, and then found that a string with "jquery" returned false!

Copying this string, we output as follows:

Attach the source code first:

Program - 副本.cs (725 Bytes, Number of downloads: 2)

Let's open it in Notepad++ UTF-8 format as shown below:

We didn't find any problems, so we opened it with ANSI encoding, as shown in the figure below:

We output ASCII as follows:

Login is visible.

Finally, test 8203, 8204, 8205 to char, write to the file, there will be strings that are not visible to the naked eye. Now I'm confused.

In the properties dialog, the path copied by the security tab VS is also not recognized, it will always make errors, and it will not be visible to the naked eye
