Code 128 characters code#

Multiple segments with different code sets can be used in a single barcode.

Code 128 characters manual#

It is also possible to select the manual mode where the character code (^A, ^B, ^C, or ^S) for the different modes must be entered by the user as the first character of the segment of barcode data using that code set. Therefore, 100 of the 102 characters in code set C are used to represent the 100 two-character combinations from 00 through 99.Д«arTender allows selection of any of these code sets or an auto mode that will determine the best mode for the data entered. This character set is numeric-only, but any one character actually represents two digits.

Code 128 characters full#

The three character code sets can be summarized as follows:Д¬ode A: The Full ASCII set, except for the 26 lower case letters.Д¬ode B: The Full ASCII set, except for the 26 'control' characters.Д¬ode C: Double-density numeric.

Because it is possible to use any combination of the three character sets in a single barcode, Code 128 gives you the greatest possible character density when encoding data into barcode. However, once a Circular Code 128 barcode is started, it is possible to switch between the different character sets in the middle of the barcode. The default character set in use for any Code 128 barcode is determined by the start character. This is possible because Circular Code 128 actually contains three different sets of 102 characters. Although Circular Code 128 can encode all 128 lower ASCII characters, the character set itself contains only 102 characters. You can repeat the double FNC4 characters to revert back to non-extended values.ДЇor instance, to encode GrГјГџe, you would do the following: If you plan to encode more than 1 subsequent character, you can use two consecutive FNC4 characters to latch into the extended values. The FNC4 code acts as a toggle for only a single character. In order to support extended ASCII characters such as Гј (u-umlaut/diaeresis) or Гџ (eszett), you have to precede the character by an FNC4 then subtract the unicode point of the character by 128. This class inherits the BCGBarcode1D class.

array(array(BCGcode128::CODE128_C, '012345'), 'auto encoding') : multiple encoding method.

array(BCGcode128::CODE128_C, '012345') : Table C The full (128-character) ASCII character set can be encoded in this symbology without the double characters found in extended Code 39.

auto encoding : automatic encoding method.

You can also still force the encoding method below are the possibilities you can pass to the parse() method: You can pass normal text to the method parse() in order to let this method analyze your text and choose the best encoding method. You can write them by activating the tilde character (~) with the setTilde() method.

These are the characters FNC1, FNC2, FNC3, and FNC4. Table C : Group numbers by 2 from 00 to 99Д¬ode 128 also contains 4 special characters that can't be written directly.Table B : ASCII 32-127 (capital letters, lower case, numbers, special characters).Table A : ASCII 0-95 (capital letters, numbers, special characters).Here is a list of the supported table characters: If you don't specify a specific table, the table is automatically chosen. You can select the table when you start your code, it is a good choice to choose a table which contains the first characters you want to write. When a character is not available in the table, a 'change table' character is written. Different encoding tables allow you to encode data more efficiently. Code 128 allows you to encode all the ASCII characters from 0 to 127.
