I'm not sure, but my gut instinct is that it wouldn't help. Dyslexia rates are much lower in China, so if I suppose we could start naming files with Chinese characters (on systems that support Unicode). It would take a bit to get used to, but eventually we'd develop a pidgin language for when we talk about software, much like how if you overhear Chinese or Vietnamese developers they will mix in English words like "linked list" into their sentences, because there's not a more natural sounding alternative.

Switching to Chinese would also help eliminate the spaces issue.
