I don't really understand how Charlotte (with the emphasis on Char) shortens to Lottie anyway. It's not a 'natural' shortening.
It's not a 'shortening'...it's a nickname. Not the same thing. Like Charlie/Charles. 'Charlie' being 2 syllables so 'longer' than one syllable 'Charles'...both with the same number of letters!
There are lots of nicknames that sound nothing like the name...Betty for Elizabeth, with its hard 'tty' instead of soft 'th' on the end, or Billy for William.
Some are far more obscure but still nicknames...Daisy/Margaret 🤷♀️ (because the French word for 'Daisy' is marguerite...so 'Daisy' became a common nickname for girls called Margaret...my Nan was one such!)
