I can convert the c to k but I want to convert the block to bold. The unicode is u8080 and u8081.

// *** Write to file ***

// Specify file, instructions, and privelegdes
FileStream file = new FileStream("C:\\share\\test.txt", FileMode.OpenOrCreate, FileAccess.Write);

// Create a new stream to write to the file
StreamWriter sw = new StreamWriter(file);



//string ublka = "\u8080";
//string bldo = "<b>";

string ublka = "c";
string bldo = "k";


// Write a string to the file
sw.Write(sourceResult.Description.Replace(ublka,bldo));

// Close StreamWriter
sw.Close();

// Close file
//file.Close();

Thanks,
David
