Using illegal characters in id-ne fields

[jonwimp]

Is it absolutely wrong to use illegal characters in productId field?

What are the reasons not to use illegal characters in productId?

I encountered one: Javascript function names don't work with ' ' (spaces), so the QuickAddVariants
page is broken if you use ProductFeature(s) with Id(s) that contain spaces.

Am doing a data migration, so I encounter illegal characters.

There are all sorts of problems with such characters. Most of them  
are related to web-related standards like HTTP (especially in URLs  
and URL parameters), and like you mentioned in JavaScript, and of  
course both of these are related to HTML.

It's generally a good practice anyway to use a pretty limited set of  
characters for IDs. You never know what you'll want to do in the  
future, like maybe print it as a barcode or something... and  
depending on the barcode standard you go with you'll have a varying  
set of characters available.
