1.1. The problem of invalid characters when the page title is saved as a file. 1

1.2. Replace with Chinese full-width symbol (recommended, readability is best) 1

1.3. Use Escape (recommended) ... 1

1.4. Use the UrlEncode mode (simplest, readability generally) 1

2. Code 1

2.1. code--full-width symbol 1

1.1. The problem of invalid characters when a page title is saved as a file .

Usually two processing methods::: Replace into a space or use escape (recommended) ...

Invalid file name for Windows characters .../\:* <>\ "| Slash, backslash, colon, asterisk, question mark, left and right angle brackets double quote vertical slash

Angle brackets, double quotes, tree bars ... And ... "." A point and a "..." The two points are used to denote both the current directory and the parent directory, so they cannot be used as filenames

Linux is basically only a backslash ...
