Absolutely not. But you can, if you want 

#define → ->

And you are set.

Actually, no. Per [cpp.pre], macro names are required to be identifiers and, per [lex.name], U+2192 (RIGHTWARDS ARROW) is not among the characters that are allowed in identifiers, even prior to the acceptance of P1949 for C++ and N2836 for C. As can be seen here, that character does not have the XID_Start property.

We might eventually want to adopt a subset of such non-identifier characters for use as operators in C and C++ and, perhaps as part of a more encompassing proposal, it would make sense to dedicate this character as an alias of the -> operator if only to prevent it from being used for other purposes. But I think this proposal on its own lacks sufficient motivation at this time.

Dear all,

Even if it looks anecdotal, I would like to suggest support for unicode
right arrow character → as a valid substitution for ->.
