> Something appears wrong with both the FILE and LEN functions
> This bit of dialplan shows some examples: (edited to replace code with links as this trackers messes up code)

> ...produces this output: (tidied only for posting) - this is messed up in so many ways.

> LEN is showing the wrong length. 
> 1 character gets a weird character added.
> 23, and 4  characters OK
> 5 characters loses a character - BUT LOOK! Even though hexdump prints the correct contents and length, have a close look at this: 35|12345|  whereas normally it would have a space before the pipe.
> 6 characters is OK
>  (by the way, Component with id 'functions/func_len' does not exist)
