If the book is your responsibility, before you start, make sure it will be cleared for copyright purposes.
Every line starts at the left margin.
It's OK to indent a few spaces for poetry and other special events, but never use the tab key for this, just the space key. Don't insert 2 spaces after all periods unless you want to chase down all the extra spaces following etc. You may substitute words for symbols, or use the English version of the letters, or substitute if you don't want to transliterate. Ligatures like AEsop can become Aesop. If the book is full of dialect and deliberate misspellings, you'll have to be VERY careful about reading the book and not just running over it quickly with a spellcheck program.
