Yes, it's quite confusing, I don't like to use it. 

Diacritic: "a glyph added to a letter" (a+`=à, ’+e=é…). 
But "diacritical search" means nothing to me if "sensitive or insensitive" 
isn't mentioned. 
Here they do it and it's not confusing: 
<https://msdn.microsoft.com/en-us/library/windows/desktop/bb231283(v=vs.85).aspx>

Ligature: "two or more graphemes or letters are joined as a single glyph" 
(o+e=œ, a+e=æ…). 
In french 4D, search correctly compares some of these. 
They are not diacritics, as far as I know. 

I suppose other langages have their own particularities. 

All this to say that I prefer to say "strict", it's short and obvious it is 
"strict comparison of char code". And "not strict" takes in account various 
rules depending on various langages.
