How to encode a TAB for Code 128 using the FileMaker Font Encoder on Mac?


I am attempting to use your barcode encoding plug-in and Universal Font packages to produce barcodes in Filemaker. I am attempting to combine 2 text fields into a single barcode with a tab character in the middle and when read use this tab to enter the data into two new fields. However the tab character is being ignored when read and both sets of text characters are being read into one field. The content of the text is correct. I am using the two steps to produce the bar code. The first step uses a Filemaker calculation field with the following entry:- TextIn1 & "~009" & TextIn2 & "|1", where TextIn1 is the first input text field and TextIn2 the second. I have derived the content of this field from you web page 'Filemaker Barcode Font ENcoder Plug-In' page. As you can see I am, I believe, enabling the ApplyTilde option. This result is then encoded in a second calculation field using the formula IDAu_Uni_C128( BarCodeTotal_Basic ) where BarCodeTotal_Basic is the field containing the above calculation.
Am I doing something wrong or am I misinterpreting the way the tab character is meant to work?

Operating System: Mac OS 10.6.8

Application: Filemaker pro Advanced

Referring to the IDAu_Uni_ section of the FileMaker Barcode Font Encoder Plug-in Tutorial, the function is in the form of IDAu_Uni_C128(DataToEncode | ApplyTilde), where "DataToEncode | ApplyTilde" is a single string.

Barcode Encoding:
As a test, IDAutomation recommends hard-coding the data. As an example, use IDAu_Uni_C128 ("AlphaNumericOne~009AlphaNumericTwo|1"), where AlphaNumericOne and AlphaNumericTwo are your field's string equivalent to hard-code for the test.

Universal Code 128 handles two parameters, DataToEncode and ApplyTilde. Separate parameters with the pipe symbol.

Example 1 using your variable:

IDAu_Uni_C128( BarCodeTotal_Basic|1)


Example 2 using hard coded data:

IDAu_Uni_C128( "123~009456|1")

James's answer does not work. The tab character is still not recognised in the hard coded option, all data is entered into a single field. I need the tab character to move the entry point to a second field. A manual tab in Filemaker does this. As for the first option, IDAu_Uni_C128( BarCodeTotal_Basic|1 ), Filemaker immediately start looking for a field with the name 'BarCodeTotal_Basic|1' which it cannot find. The only way Filemaker would accept this is as a Filemaker text calculation of BarCodeTotal_Basic & "|1" which will combine the text contained in BarCodeTotal_Basic with |1.

So far getting a tab character to switch fields is not working.
