For some reason, Acer did store the manufacturer and product in my Acer Aspire One as:


And when outputting this to the screen, the added spaces look weird:


I found several settings types which convert the data, e.g. uristring, hex, etc. ... but I didn't find a way to just trim the excessive spaces.

I found this discussion on the mailing list, but the mentioned trick doesn't work anymore and there's no other solution to the problem in that thread. There was also a proposal for a new "trim" command, but that's where the thread ended.

Is there a way to trim whitespaces?

String manipulation functions have not been implemented as we're still discussing how they should be provided to the end-user (API). For now you'll need to send it to a server-side scripting language via HTTP (GET parameters) and truncate them and return a script with them cleaned.

Any progress on this?

Unfortunately the patch does seem to break on efi in particular situations.
I'm working on a way to resolve this.
