A sequence should not be treated as "strange" sequence if it has been
written intentionally. It may have some contextual meaning.

Not only that, but it is also desirable. How can one write a vowel matra
both with and without dotted circle in a single document if Unicode
recommends to place it only on top of space character? Matra with dotted
circle is sometimes useful as in the case of printing/explaining Unicode
standard. A user may want to hide dotted circle in the same document in
order to explain the actual shape of the matra character, i.e., without
dotted circle. Both kind of rendering behaviour is possible. There should
be some mechanism either to turn on or off dotted circle depending on the
Also, what is good or bad is also subjective. It may also vary from one
