If your child is bilingual then go ahead and use the material they would use if they attended school in the other country. That's what we do with our children.
If your child is older and learning a new language chances are he/she will pick up the spelling while learning new words. At least that's my personal experience.
As for your question. No, not all languages are taught the same way like English. There may be no special words to learn or start with especially if the language is fairly phonetic. There may be lots of rules but the basics can be quite simple and go hand in hand with learning to read.
