Power BI model should be case-sensitive to the imported data

Currently, Power BI model currently uses a locale that is not case-sensitive (or kana-sensitive) so "ABC" and "abc" will be treated as equivalent. If "ABC" is loaded into the database first, other strings that differ only by case such as "Abc" won't be loaded as a separate value.

Power BI model should use or alter its current locale so that it is case-sentitive.
It should be able to distinguish uppercase letters and lowercase letters and be shown as such.
