ASCII Chart | ISO 1252 Latin-1 Char Set

The following table is a mapping of characters used in the standard ASCII and ISO Latin-1 1252 character set standard. The decimal “Dec” column may be used to locate the number for ApplyTilde and ProcessTilde functions in IDAutomation Barcode Fonts, Components and Label Printing Software.

The first 128 characters are referred to as US-ASCII and are the same in all countries and locales. Characters above 128 in this chart are unique to the ISO Latin-1 1252 character set and vary depending on country and locale settings. Unicode refers to a common character set that is the same for all systems, countries and locales. To properly encode Unicode characters above 0x7f in a barcode such as Data Matrix or QR Code, a conversion to UTF-8 is necessary.

The characters from ASCII 0 to 31 are commonly referred to as function characters because they perform functions instead of a printed characters. Normally, these characters are not visible unless an application is used such as IDAutomation’s Barcode Scanner ASCII String Decoder. Common function codes are 9 which creates a tab and 13 which performs a return. The ^ in the Char column refers to the control (CTRL) key. For example, CTRL-G is ASCII 7 which creates a bell sound and CRTL-M is a new line, referred to as a carriage return.
