I couldn't find a reference to how this is supposed to work, but I'm hoping somebody can clarify/elaborate on this.
In IW21 (and probably others), the long description field replaces spaces with '+' plus signs, but only sometimes. This seems to only happen using the GUI for HTML.
Why does this happen?
For example, when using the values below in the full description, they only change sometimes.
'This is a test' => 'This+is+a+test'
'This + is a test with + plus signs' => no change
'This is a test
with a line break' => no change
