In Item5453 a general issue is raised which is that some macros are not handling the value 0 as a string but as the value false.

This causes for example ENCODE to convert 0 to ''

As Sven rightfully says this can be a can of worms.

But I believe the best is to take them one at a time - and take the first one as the one that seems to have caused problems already in reports.

And the 5453 reports the ENCODE as the problem

I could not follow up with unit tests etc and other may follow up. I think a simple little comment in the code where I fix it will prevent the bug from coming back.

I will checkin the school book fix for how to handle a variable that can be 0.

The general way is

$a = defined ( $b ) ? $b : '';

I create this bug report so I can put it Waiting for Release and get the happy news about ENCODE in the release note.

If I check in on 5453 I cannot close the bug and it will not be in the release note.
