Text module: can't use "#" symbol

[Pumice]

Not sure if this needs more description. Using the text module, can't seem to use the # symbol, it results in a "0" placed on the image where the number symbol should be.

For example, a file with the name 123456.jpg:
Item #: {Filename}

Would result in the following text added to the image:
Item 0: 123456

'#' is the numeric enumerator, so it's file's index not filename
