I think that you touched one of the reasons why not all unicode characters are supported. You said that it is not recommended to use identifiers with confusables because they will be wasting the time of the SR user. Imagine though that someone decides to write an entire text in english using lets say the french or german alphabet, putting accented or umlauded letters everywhere where it is possible. Now, one can say "lets convert the confusable to the main form and read it like that", but what happens if you stumble upon a new text where there is a meaningful difference between the accented and not accented letters? The situation is not hypothetical, because very often one can find either a multilanguage document or a book with with names and single words in another language.
