How to delete everything from string after character "/u"? [duplicate]

Question

Hi i have strange problem. Here is my code:

string tmp = "20_29\u0013";

How can I get rid of that "\u0013"?

Normally I will do it with substring or something but I have some issues with that character ---> \
Could someone help me?

Where did this come from? \u0013 is an escape sequence representing the carriage return character — Panagiotis Kanavos

It is from my client which is sending data to my server. TCP\IP — Brarord

technically, tmp = tmp.Replace("\u0013", ""); where "\u0013" is in fact a single character with 0x0013 code: '\r'. Another possibility is tmp = tmp.TrimEnd(); which removes white spaces ('\r' included) from the end of the string — Dmitrii Bychenko

Does the client send `, u, 0, 0, 1, 3` ? Or a single 0x13 byte? This escape sequence is a carriage return, also represented as \r. In all single-byte code pages and UTF8 it's represented by a single byte, 0x13. You can remove it from the end of any string with Strings.TrimEnd('\r', '\n'); — Panagiotis Kanavos

You can use tmp.TrimEnd('\u0013') if it is single char or tmp.Replace("\\u0013", string.Empty) if it is sequence of chars to get "20_29" part:

Everything is a Unicode character. This particular character though is an ASCII character - a carriage return \r

Yes, I mean that '\u0013' is one solid character (not string of characters), so you can use IndexOf on it

Or use TrimEnd

Yes, TrimEnd is perfect choice here
