[TF-dev] Double or single, that is the question

Hello everybody,
I have two related questions.
In "NetBeans_6.7_msghtml_javase" project on CTI should I always put a single apostrophe even if a {1} tag is present?
In "NetBeans_6.7_properties_platform_javase" project should I put double apostrophe where tags such as \{0\} appear and single where they don't?
Note that in the first case I didn't escape the braces (as it actually appears on CTI); so, even if  don't know the precise implementation reasons, I thought that there could have been a difference in quote escaping too. In Italian it is quite usual to truncate and join words (e.g. "the installation" becomes "l'installazione") so the answer is very important!
Thank you and regards,
Filippo

P.S. @Masaki
I checked the js file on the Mercurial repository you linked me. It seems ok to me now so let's wait to see the download page.
