Special symbols and punctuation should only be included when absolutely necessary. For example, an apostrophe is included in English words like “don’t” and “we’re” and should be included in the source text, but it’s unlikely you’ll ever need a special symbol like “@” or “#.”
Symbolos special e punctuation deberea solo esser includite si absolutemente necessari. Per exemplo, un apostropho es includite in vocabulos anglese como “don’t” e “we’re” e debe esser includite in le texto fonte, ma il es inverisimile que tu unquam besoniara de un symbolo special como “@” o “#.”
