Considering two kanjis that can be used in the same situation, can they convey different styles of writing, one more formal and one more informal, or are they completely the same? (I know sometimes they can convey slightly different meanings, but it’s not quite what I’m referring to).
The doubt came up when I wrote 才 instead of 歳 in a sentence, but I’d like to know in general, thanks.
