Here's an example of a possible problem with a Latin script language, Igbo, which has a low dot diacritic below vowels. In the image below the left sequence has a combining dot below, and the right doesn't.

Here's an Igbo word where it's hard to be sure whether a dot below is used or not.

It is, however, a little easier to spot the distinction in some fonts than others (ie. it's easier where the font makes the dot below more round, or where the letters are wider).  The font used above is Arial Unicode.

There are also situations where the meaning is not so hard to detect, but the shortness of the underline is for me a little ugly. I wonder if these would be improved by not trying to underline the vowel at all.(?)

For example, here are a couple of Vietnamese words in Noto Sans font with very short underline fragments (the small dots to the right of the dot below).

and another African language
