Extended ASCII - Latin G (Latin Graphic)

Each column of the table shows the lower nibble (Hexadecimal x0-xF) of the character byte.

Each row of the table shows the upper nibble (Hexadecimal 0x-Fx) of the character byte.

Lower case "k", would therefore be represented by the byte 6B in hexadecimal (107 in decimal).

And possibly some more languages as well.

The base languages are the main ones the character set is covering.
The extended languages add a few extra characters so that they are
fully covered.
The concomitant languages, just happen to be fully covered because
they use the characters from the base and extended languages.
The character set tries to fully cover the western and northern
European languages which have an alphabet mainly derived from Latin.

Using the extended ASCII character set

The extended part of the encoding (128-255) is laid out in a similar way to the ASCII upper and lower case letters, but with two sections rather than one. This facilitates moving between upper and lower case letters by adding 32, and subtracting 32 to go from lower case to upper case. The below outlines simple calculations which can be used to arrive at the extended character, starting from the ASCII letter. e.g. "Á" is got by taking ASCII upper case "A" and adding 64 to it. To go from "Á" to the lower case form, add 32 and get "á", just like going from ASCII "A" to lower case ASCII "a". The simple calculations for diacritics, ligatures and special characters, only apply to the ones supported in the extended character set.

This encoding is a subset of UTF-8, in that all characters come from UTF-8, so can be translated to/from UTF-8 easily. When translating to UTF-8, it does not use any combining characters, each of the accented and special letters are single code points, though it does use the text variation selector to specify that some code points are represented as text by adding an additional code point (U+FE0E). When translating from UTF-8, the characters must be normalized (go through Unicode composition) first, so that more than one code point i.e. a letter with a combining diacritical mark, becomes one.
