Instead, the assembler allows the middle dot character U+00B7
and the division slash U+2215 in identifiers and rewrites them to
plain period and slash.
Within an assembler source file, the symbols above are written as
<code>fmt·Printf</code> and <code>math∕rand·Int</code>.
The assembly listings generated by the compilers when using the <code>-S</code> flag
show the period and slash directly instead of the Unicode replacements
required by the assemblers.
