How do I translate 8bit characters into 7bit characters? (i.e. Ü to U)

Question

I\'m looking for pseudocode, or sample code, to convert higher bit ascii characters (like, Ü which is extended ascii 154) into U (which is ascii 85).

My initial gues

Answer 1

The upper 128 characters do not have standard meanings. They can take different interpretations (code pages) depending on the user's language.

For example, see Portuguese versus French Canadian

Unless you know the code page, your "translation" will be wrong sometimes.

If you are going to assume a certain code page (e.g. the original IBM code page) then a translation array will work, but for true international users, it will be wrong a lot.

This is one reason why unicode is favored over the older system of code pages.

Strictly speaking, ASCII is only 7 bits.
