Question: When I type any word ending with an 'l' (ell, like "local") and then press the `/` key, the 'l' is replaced with another symbol and the slash, '/', is omitted. How can I deactivate that function?

Answer: 
This looks like the behavior of some very old Mac fonts (Palatino was one of them) where you could make the character l with stroke (used in Polish and elsewhere) by typing such a sequence. Try changing your font. If this is in fact the cause of the problem, you should get rid of the font that does this, which should not be on any modern mac.
This looks to me like a rendering bug rather than a feature. I would try increasing the font size on your terminal.
