When you get Symbian, you find that the path names of the Symbian file are all connected in this way. I think about the escape character problem, another example of the code of the file system we are reading today is to check whether a row has been read. It is useless to check '/R'. It is also an issue to take a good look. Find the following content on the Internet:
An escape character is a character used to indicate special characters and non-printable characters. For example, "/" indicates that the escape character starts. to display it, use "//". For another example, the linefeed "/N" is a control character that cannot be displayed and is used to implement the line feed function. As for how to use it, because the escape character is a character, it can be used anywhere where it is used. It can be used either in a single character or in a string.
The following are special characters:
/B: Roll Back: one row backward
/F: Form feed
/N: line feed, cursor to the beginning of the downstream line
/R: Press enter and move the cursor to the beginning of the line.
/T: horizontal tabulation
/V: vertical tabulation
//: Backslash
/': Single quotes
/": Double quotation marks
/? : Question mark
/DDD: three octal nodes
/Xhh: two-digit hexadecimal format
/0: NULL)
