# Some facts#

• ASCII (American Standard Code for Information Interchange) is a standard describing how characters are stored (encoded) inside computers. The standard defines mapping of letters, ciphers (numbers), some special characters such as a period, comma and control flow characters.
• ASCII maps each character (e.g. The letter 'a') to a number between 0-127. Characters encoded this way can be transmitted between different devices. If both of them use ASCII standard, then transmitted stream of data is understood and interpreted in the same, standarized way.
• Pure ASCII supports english-latin alphabet only. This limit caused development of many extensions of ASCII standard. These systems added support for local characters like german, polish or chinese alphabets. For example Mazovia was extending ASCII to support polish letters and JIS (Japanese Industrial Standardsdający) was giving support for Japanese alphabet.
• Existence of many incompatible extended systems at the same time caused works on single, unified standard. At the beginning of 90's the UTF-8 standard (UNICODE 8-bit) was developed which is nowadays most popular extension of ASCII.
• ASCII set in range 32 - 126 (0x20 - 0x7E) equals to UNICODE (0x20 → U+0020, 0x21 → U+0021, etc.)
• "new line" is platform dependent:
• unix (linux) - ASCII 10 (hex: 0A) (programming: \n)
• windows - ASCII 13 10 (hex: 0D 0A) (programming: \r\n)
• mac - ASCII 13 (hex: 0D) (programming: \r)
• HTML entity &apos; is:
• valid in HTML 5
• invalid in HTML 4 - and &quot; should be used instead
• some webmasters use just &#39;
• was introduced by Ms Internet Explorer and for some time was recognized by IE only

• If you're interested in various ways of coding information check out our other calculators:
• URL encoding (sometimes called percent-encoding) - used mainly when sending www addresses and forms during HTTP(S) queries,
• BASE64 encoding - a popular way of sending binary data on the internet using protocols originally designed as text,
• Braille alphabet - a way of encoding text using convex points arranged on a plane, designed for the blind people,
• Morse code - a way of writing textual information using pulses of different length, e.g. electric or light, formerly used in telegraphy,
• punycode - a way to encode internet domains containing international characters ouside of Latin alphabet.
