Unicode's policy is to disregard combining marks for overlays (as
opposed to other categories of combining marks) and code the relevant
combined glyph anyway. That goes for letters that are members for
alphabets and is done for a number of reasons that all equally well
apply to currency symbols. So, the short answer is that even with many
overly marks already defined, these would be disregarded as would any
They are generically useful in some cases, such as to indicate negation
for arbitrary mathematical symbols and the like, but not to compose
