Where did we get this function from? Whats magical about char-code 128, 159, 189, 190, and 191? Aren’t we assuming a certain character encoding with this function?
More of my research on this. It turns out that at least in Windows encoding:
- 159 is a Y with two dots on top of it
Ÿ - 189 is the one-half sign
½ - 190 is the 3/4 sign
¾ - 191 is the inverted question mark
¿.
My again I don’t know why these characters are treated separately? Why not
195×which stands for an A with a ~ on top of it.
