Abbreviations of languages

Now there are follow abbreviations for the languages (it is indicated the number of letters in parentheses; see template:eng and so on): eng (3), fr (2), esp (3), ru (2). I think, that it is necessity to go to the same standard, e.g. to take biliteral abbreviations: en, fr, es, ru (as it was taken on Wikipedia). What do you think about this?
I don't mind. I suggest just leaving it as it is now. There is no need to copy Wikipedia exactly.
This is not coping Wikipedia, I mentioned this encyclopaedia only as example. Just different lengths of abbreviations, as for me, are looking not very good. And it is a bit strange.
I agree with Bertran - we need to follow one set of language codes, ISO 639-1 probably being the best option. The language templates should be predictable - if a user sees that the French template is called "fr", then they should be able to correctly predict that the English template is called "en" and not "eng".
