ASCII Chart

v1.0, 2003-10-27 | ASCII 0-255 | UTF-8 2-byte | UTF-8 3-byte | UTF-8 4-byte

This is the original ASCII Character Chart I made back in 2003. The original 256 ASCII characters served most of the world and each character could be represented with an 8-bit number. The most common characters were placed below 127 so they only needed 7 bits. This was important when computers were all based on 8-bit technology. If you look closely, you'll notice you can add 32 (bit 5) to any uppercase letter to get the same lowercase letter.

Since then, computers have evolved, along with the internet. Modern character sets like UTF-8 use 16, 32, and 64 bit encoding, while remaining backwards compatible with the first 127 characters of the original ASCII set. Jump to the next page, UTF-8 2-byte Characters to see the transition.

Notes and Examples

• The Decimal ASCII value is underneath each character, i.e. "N" = 78
• The Hexadecimal ASCII value is the row# and column#, i.e. "N" = 4E
• To display "16² = 256", the HTML is: 16² = 256
• To display "PULPchat®", the HTML is: PULPchat®
• The decimal ASCII value of a lowercase letter is the uppercase letter + 32.
• ASCII 13 is Carriage Return (CR), \r or 

• ASCII 10 is Newline (LF), \n or 

• ASCII 9 is Tab, \t or 	
• ASCII 8 is Backspace, \b or 
• ASCII 12 is Form feed, \f or
