You have the correct idea on trimming: just 
use -trim()-. 

I am not clear why you want explicit double 
quotes as part of the string, but you 
can do it this way. 

Example: 

sysuse auto 
gen make2 = `"""' + make + `"""' 

That is, in each case, you need 

a delimiter that is `" 
the character itself, " 
a delimiter that is "' 

The single quotes are left single 
quote and right single quote. 

Compound double quotes are discussed 
at [U] 18.3.5. 

This also works: 

gen make3 = char(34) + make + char(34)
