@alain01,
First my disclaimer - I am not a lawyer, and as such, am not giving legal advice, just my opinion of what the document says.
The fact that you are looking at the "CC BY 3.0 US" just means this is the English version of the Creative Common license.
If you look at paragraph 3 it says:
Quote:
3. License Grant. Subject to the terms and conditions of this License, Licensor hereby grants You a worldwide, royalty-free, non-exclusive, perpetual (for the duration of the applicable copyright) license to exercise the rights in the Work as stated below:
The license is not intended to limit your distribution by global region.
You'll still need to make sure what you want to do meets the remaining items in the license to be able to distribute the icon set.
