The quick solution for that problem is as follows:
1. open in Dreamwaver [language].php file
i just did exactly that and it doesn't work for me!
portuguese letters like "á" or "ç" doesn't show properly on my browser after uploading the language file.
so i returned to the solution i already mentioned some postings above:
transform all those special letters into html code (ex. "á" ---> "á").
then set the language of your gallery to "english" (for example) and character encoding to "utf-8".
that works fine for me!

i repeat: many thanks to all translators!!! but let me say only one thing: let's just be realistic. do we really need so many languages? how many visitors does your gallery get? millions? from all of the world? there are big enterprises whose very professional websites don't have so many languages! why should "normal" human beings webmasters like us need so many languages?
most of the coppermine language is "navigation" language. i think today maybe 90% of the people who surf on the internet can understand "navigation english" anyway.
so i think if someone wants more than one language on his gallery he should take english as the main language and the language of his own country, which he would revise for errors or adapt for his needs. that would be enough instead of having dozens of languages whose translations may not be accurate or free of mistakes and typing errors and which we will be never able to verify.
on my gallery i use only 3 languages.
and i'm happy!
