Telepen

Telepen

Telepen is an arbitrary length barcode symbology for encoding all 128 ASCII characters without the need for shift characters.

Also known as: Telepen Alpha, Telepen Full ASCII.

Uses:

• Library books and library cards, chiefly in UK libraries.

Variants:

• Telepen Numeric is a variant for efficient encoding of numeric data.

Standards: USS Telepen.

Data and Options

• The data can contain any standard ASCII data, values 0-127.
• When the parse option is specified, any instances of ^NNN in the data field are replaced with their equivalent ASCII value, useful for specifying unprintable characters.
• The aimstartstop option uses the start and stop characters of the AIM Uniform Symbology Specification, which tell a reader whether the symbol contains compressed numeric data. With it, ^016 (DLE) in the data, using the parse option, switches the rest of the data to compressed numeric digit pairs. It cannot be the first character.
• The mandatory check digit is automatically included.
• Deprecated: Use Telepen Numeric instead. When the numeric option is given, the data is read as either pairs of digits or 0X, 1X, etc. The singular values ^000 to ^015 and ^127 can also be encoded using the parse option.

Examples

A basic symbol:

Data:    Telepen
Options: includetext
Encoder: telepen

A symbol using the parse option to encode a carriage return:

Data:    Telepen^013
Options: parse
Encoder: telepen
