  Sample input:
Char0 ()
  Sample output:
String containing a \0x00

  Function definition: (Copy & paste into FileMaker's Edit Custom Function window)

Especially from FMP11 bases, some fields contains a char(0) inside the field. Sure how it got there, but difficult to clean - and creates potential problems when exporting to various file formats, like XML. The XML becomes invalid.

As the constant char(0) is treated as an empty string, you cannot use it as an argument in a substitute function. Instead use this function, or write Base64Decode ( "AA==" ) that returns a string containing a single character 0.

For FileMaker versions before 14, this function is absent, but you can use the free BaseElements plugin instead, having BE_base64_decode function that works in exactly the same way.
