A possible solution:

In get.e and std/get.e

... 
constant DIGITS = "0123456789", 
	 HEX_DIGITS = DIGITS & "ABCDEF", 
	 START_NUMERIC = DIGITS & "-+.#", 
	-- Added - Valid start characters for an euphoria object 
	 VALID_START = START_NUMERIC & {'{','\"','\''} 
... 
char ch  -- the current character 
ch = GET_EOF  -- Added - Initialize to an invalid start character 
... 

In get.e

global function get(integer file) 
... 
    input_file = file 
    input_string = 0 
    if not find(ch, VALID_START) then	-- added to preserve ch if start character 
	get_ch() -- discards only if ch is an invalid start character (separator) 
    end if 
    return Get() 
end function 
 
global function value(sequence string) 
... 
    input_string = string 
    string_next = 1 
    if not find(ch, VALID_START) then	-- added - preserve ch if is a start character 
	get_ch() -- discards only if ch is an invalid start character (separator) 
    end if 
    return Get() 
end function 

In std/get.e

function Get2() 
... 
    -- init 
    offset = string_next-1 
--  get_ch()  -- comment out, same behavior as Get() 
... 
 
function get_value() 
... 
-- Why different behavior for Get and Get2?, removed if (see Get2) 
--  if answer_type = GET_SHORT_ANSWER then 
    if not find(ch, VALID_START) then	-- added - preserve ch if is a start character 
        get_ch() -- discard only if ch is an invalid start character (separator) 
    end if 
    return call_func(answer_type, {}) 
end function 

It's correct?
