Burton had an extensive vocabulary. Before correcting a 'spelling mistake', it may be worth looking the word up in a good dictionary. For example, hent, cark, blee, stround, dight are all words that appear in the Nights. All are also actual English words. Finally, about spelling.
Many spellings are British vice the American ones.
For example, colour, honour, programme. I'd like to retain the British spellings. I can handle just about anything. If you wish to create a second file, containing the correct diacritical marks, Greek, Arabic, etc. A version of the Nights containing, as much as is possable, all of the specical characters, diacritical marks, itallics, Greek, etc. is also being created.
