It's nice to see a good selection of currency symbols defined in
unicode, but I wonder if it might be useful to add a few combining
marks for the purpose of constructing currency symbols.
For example, many currency symbols use single or double horizontal
lines, vertical lines or solidi ( |, -, /, ||, =, // ). Having these
available as combining marks would simplify the creation of new
currency symbols, as many are simply overstruck letters.
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
additional ones.
They are generically useful in some cases, such as to indicate negation
for arbitrary mathematical symbols and the like, but not to compose
letterlike glyphs.
