does anyone do due diligence on corporate names before launching? Sakana is a popular slang spelling of sacana, or bastard, in Português. I suppose self modifying code can be considered such, in some circumstances, but willingly pointing this out is probably less than stellar marketing.
Does it matter? Maybe you should check English, Chinese and Spanish for some really offensive stuff, but past that... would it bring more money than a week or so of someone's work would cost?
The answers to those questions should be known concretely at least.
You never know when you start out a company. Maybe you'll never get any profit and it doesn't matter. Maybe you lose out on a few millions out of billions... and maybe it still doesn't matter? Then you can still release a locale-specific version if it becomes a problem.
Maybe you lose out on Brazil.
Reminds me of Ford when they brought the Pinto to Brazil.
