well -- I can live with 'i', but if I came across code using variable names
i, \'{\i}, \`{\i} and also \i, \u{\i}, \r{\i}, \d{\i} etc. I'd consider that
dangerous to my sanity (especially if they're all used in the same piece of
code)... ;-)
More seriously, as I (literally) see it, the problems of confusing l / I / 1
or O / 0 etc. are reasonably solvable by using a decent font (e.g. Deja Vu,
Source Code Pro), but ensuring distinctness of glyphs in the same way
won't scale to character sets the size of Unicode.
