Macron below
Macron below is a combining diacritical mark that is used in various orthographies.
A non-combining form is U+02CD ˍ MODIFIER LETTER LOW MACRON. It is not to be confused with U+0320 ◌̠ COMBINING MINUS SIGN BELOW, U+0332 ◌̲ COMBINING LOW LINE and U+005F _ LOW LINE. The difference between "macron below" and "low line" is that the latter results in an unbroken underline when it is run together: compare a̱ḇc̱ and a̲b̲c̲ (only the latter should look like abc).
