Macron below

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).

Thus, U+1E07 ḇ LATIN SMALL LETTER B WITH LINE BELOW decomposes to U+0062 b LATIN SMALL LETTER B and U+0331 ◌̱ COMBINING MACRON BELOW.
