The following ASCII table contains both ASCII control characters, ASCII printable characters and the extended ASCII character set ISO , also called ISO. The following ASCII table with hex, octal, html, binary and decimal chart both the ASCII control characters, ASCII printable characters and the extended ASCII. ASCII Table - Standard and Extended ASCII Chart, ASCII Codes. ASCII stands for American Standard Code for Information Interchange. It ranges from 0 to in Decimal or 00 to FF in Hexadecimal. ASCII codes can be divided into two sets - Standard ASCII codes and Extended ASCII codes.

The number of printable characters extended ascii table deliberately kept small, to keep teleprinters and line printers inexpensive. Some popular peripherals only implemented a printing-character subset: The biggest problem for computer users around the world was other alphabets.

ASCII's English alphabet almost accommodates European languages, if extended ascii table letters are replaced by non-accented letters or two-character approximations.

Languages with dissimilar basic alphabets could use transliteration.

Users were not comfortable with such compromises. At least 29 variant sets resulted. There was always temptation to make a larger character set preferably by extending a standard character setextended ascii table there was no easy path forward.

There was no way to define a universal extension. There was no hardware to print or display an extended set.

What is extended ASCII? Webopedia Definition

The English alphabet was generally useful on computers around the world for programming, operation, and international communication, so extended character sets that added to the original ASCII set were a good idea.

When computers and peripherals standardized on eight-bit bytesit became obvious that computers and software could handle text that uses character sets at almost no additional cost in programming, and no additional cost for storage.

Assuming that extended ascii table unused 8th bit of each byte was not reused in some way, such as error checking, Boolean fields, or packing 8 characters into 7 bytes. An eight-bit character set using one byte per character encodes characters, so it can include ASCII plus more characters.

But software must be more sophisticated, only accepting or creating valid multi-byte characters, and always treating multi-byte characters as extended ascii table character whenever counting, copying, comparing, inserting, or deleting characters.


Many manufacturers devised 8-bit character sets consisting of ASCII plus up to of the unused codes, extended ascii table varying degrees of cooperation or coordination by national and international standards bodies. ASCII was developed a long time ago and now the non-printing characters are rarely used for their original purpose.

Extended ASCII - Wikipedia

Below is the ASCII character table and this includes descriptions of the extended ascii table 32 non-printing extended ascii table.

So with this set of only characters was published in as standard, containing all you need to write in English language. InIBM developed an extension of 8-bit ASCII code, called "code page ", in this version were replaced some obsolete control characters for graphic characters.
