Hello,

I am replacing a string of characters in a file but i have a problem with special characters.
I use this for replace text into file

My.Computer.FileSystem.WriteAllText(path2, My.Computer.FileSystem.ReadAllText(path2).Replace(renfile7, renfile4), False, System.Text.Encoding.GetEncoding(1252))

and it works.

Original file read with Notepad ++ ANSI encoding

ÐÏà¡±á

After WriteAllText the characters replaced ????

????

I would want to leave the special characters intact, it is a problem of encoding?

You should read this:What Every Programmer Absolutely, Positively Needs to Know About Encodings and Character Sets to Work With Text[^]

1252 encoding is limited and therefor doesn't have all the characters needed.

Good luck!

Thanks, but I don't want writealltext replace the special characters but only the string i want to replace

Then you must read and write the file wioth the corrent encoding. For UTF-8 you need to specify Encoding.UTF8 as parameter both when reading and writing.

with notepad ++ I replace the string and i save the file without touch the special characters, and I can use the file .TGD , while with WriteAllText replace string is ok but it removes me special characters. Ok i try to test your solution

reading in GetEncoding (1252) works, thanks

By default ReadAllText will try to detect the encoding but fails (probably because it will try to load the text as utf-8). See link for more info.
