Enable Case sensitivity in document name and db query

Frappe Framework App Development

Hi,
i recently found that the naming of document is not case sensitive that’s mean that we could not have two doc with names ‘A’ and ‘a’ respectively.
This is appear to be the same with db query such as frappe.db.get_all method the filter conditions are not case sensitive.
for exemple if a have two docs of same type let’s say

doc_1 = {'doctype': 'foo', 'name': 'a', 'field_1': 'Field_value'} 
doc_2 = {'doctype': 'foo', 'name': 'b', 'field_1': 'field_value'}

# the below query will return doc_1 and doc_2 when only doc_2 is wanted
data = frappe.db.get_all('foo', filters={'field_1': 'field_value'})

So how could i enable case sensitivity in both cases please
Thanks
