I am aware that I make mistakes and do not follow the conventions and know nothing about the codes used for formulae so it is good when somebody edits my post. But I am curious, in this editing some real mistakes were corrected but also some words deleted and inserted as they were, at least in my browser (Firefox).
Is it possible that in other browsers some everyday characters are interpreted differently? For example, I see no difference in the spelling and settings for "telescope" and "the" in the first line.
As sometimes the spell checker does that too, I am wondering if my keyboard does something funny (it is also a greek keyboard) that others can see who do not have greek in their browser.
