This section explains the built-in XPath function:
Returns the UTF-8 characters that are specified as the hexValue input string (must be the hex codes of the characters' byte-sequence in UTF-8 encoding).
For the 2D barcodes like PDF417 and QR you might want to insert unprintable characters e.g. Hex 1D, 1E and similar as delimiters. If you want to insert such texts you can e.g. define them with this function and use concat to insert them between the variable data.
Example:
ng:hexToUtf8('616263') Displays: abc
