Why does SSMS treat two t's as one character

Question

Say I write the following select statement:

select distincttype_of_reading

And I move the cursor to either of the t's and press the key to move to the next one, it will skip over one of the t's treating the tt combination as one character.

Same as if I press delete it will delete both of the t's rather than just one. If I press backspace it will delete one at a time however.

This isnt a problem as such, im just curious as to why if at all there is an explaination?

Answer 1

It appears to be font related. The Calibri font supports ligatures and so, apparently does the 2008 editor (the 2012 editor doesn't have this issue).

So tt is being treated as a single glyph, for most purposes.
