In ASCII, there are some characters which have both a primary use and a secondary meaning as a diacritic. The idea was that the secondary meaning applies when the character is preceded or followed by the ASCII backspace control code (BS, FE0, control-H, code 8). Thus, for example, letter "e" followed by backspace followed by apostrophe (') would mean letter "e" with acute accent (�). This method has not been implemented and used widely, and it should be considered as very obsolete. However, similar methods are still sometimes used e.g. when one needs to simulate accented letters in pure US-ASCII: one just types "e'" and expects the reader or a program to take it as presenting "�". The following table summarizes how some ASCII characters were meant to have dual use: dec oct hex ASCII primary name secondary use
34 42 22 quotation mark (") diaeresis (�)
39 47 27 apostotrophe (') acute accent (�)
44 54 2C comma (,) cedilla (�)
94 136 5E upward arrow head circumflex accent (^)
126 176 7E overline tilde (~)
