Computer systems use binary numbers. That is: the number "two" times itself.

2x2x2x2x2x2x2x2x2x2 = 1024 = 1 K (2^10)

2x2x2x2x2x2x2x2x2x2X2x2x2x2x2x2x2x2x2x2 = 1048576 = M (2^20)

So one Kb (or KB) is 1024 bytes of data in a file
One MB is 1048576 bytes of data in a file.

Since the computer uses only numbers to represent everything, the alphabet and other characters are assigned a number. Capital A=65, 0 (zero number character) = 49.

The definitions exist for EVERY character you can type, including the <enter> key.
The definition of these characters is a world-wide standard, it is called ASCII. When you set your computer to use languages that have complicated sets of glyphs, the new rules (numbers for each glyph) are stored in locale settings. These are special, not ASCII usually.

The default locale is named "C". After the computer language C. That locale uses ASCII.

Computers are all about numbers and number crunching, so everything boils down to how numbers are stored in memory - they are stored as base2 numbers - binary - only ones and zeroes are allowed.

GAMMU-BACKUP(5) 						       Gammu							   GAMMU-BACKUP(5)

NAME

       gammu-backup - gammu(1) backup file format.

       The backup format is text file encoded in either ASCII or UCS-2-BE encodings.

       This file use ini file syntax, see ini.

EXAMPLES

       If  you will backup settings to Gammu text file, it will be possible to edit it. It's easy: many things in this file will be written double
       - once in Unicode, once in ASCII. When you will remove Unicode version Gammu will use ASCII on fBrestorefR (and you  can  easy  edit  ASCII
       text)  and  will  convert  it according to your OS locale. When will be available Unicode version of text, it will be used instead of ASCII
       (useful with Unicode phones - it isn't important, what locale is set in computer and no conversion Unicode -> ASCII and ASCII -> Unicode is
       done).

       You  can  use  any  editor with regular expressions function to edit backup text file. Examples of such editors can be vim or TextPad which
       both do support regular expressions.
