Extended Code 39 Barcode Fonts
Encoding the Full ASCII Character Set in Code 39
Extended Code 39 is inefficient and the barcodes can get very long for this reason, so please consider using Code 128 or PDF417 if encoding large amounts of extended characters. Scanning Returns and Tabs:To create a barcode that scans in 1234 and then a return function, !1234$M! would need to be printed. These can be combined also; for example: !12$I34$M! prints the barcode that scans 12, then a tab, 34 and then a return. Refer to the Full ASCII Chart for other codes. Note: For extended characters to scan properly, first the scanner must be programmed to accept them. About Extended Code 39 Barcode FontsThe Extended Code 39 Barcode Font was developed for users who need to print extended characters as they are on the keyboard. The start and stop character for this font is the asterisk. This Extended Code 39 is not compatible with IDAutomation Font Tools, and there are additional limitations. For example, to print a space, the ~ character must be used. Since the asterisk is still the start/stop character, /J must be used to scan an actual asterisk. The characters %$/ and + also cannot be read from this font because they are control characters. To create a readable % character, /E must be used instead. In addition to the space character, several other characters cannot be printed from the keyboard such as tabs and returns. Please review the full ASCII chart at the bottom of this page to encode these characters. Note: For extended characters to scan properly, first the scanner must be programmed to accept them. Extended Code 39 Font Character SetThe column ExtC39 Character lists the character that resides at the ASCII location, which can be used to print the corresponding symbol. The column Scans As lists the character that the scanner will scan when it is in extended mode. The ASCII and Unicode columns designate the location in either ASCII or Unicode where the barcode symbol for the character resides.
Code 39 Full ASCII ChartThe full 128 ASCII character set can be printed in accordance with ISO 646. This may also be encoded in the Code 39 barcode font using combinations of two symbol characters made up of one of the four Code 39 characters (+ $ % / ) followed by one of the 26 Code 39 barcode alphabetic characters. Note: The space character cannot be represented in a font at the ASCII location for that character. To resolve this in the Code 39 fonts, IDAutomation has moved the symbol representing the space character to the = character, and in the extended Code 39 fonts, it is moved to the ~ character.

Extended Code 39 is useful for encoding tabs, returns or lower case letters
in a barcode. There are two methods of implementing Extended Code 39; using the
