A symbol for “is pronounced the same as”

Yesterday’s blog posting made me think about the lack of a symbol for “is pronounced the same as”.

What I mean is that instead of writing that “write is pronounced the same as right“, we could just write “write ? right“.

I here used the symbol “?”, not because I think it’s ideal, but because it’s available. Other available Unicode characters based on the equal sign include the following: ? ? ? ? ? ? ?

However, ideally I think I’d want square brackets on top of an equal sign because pronunciations are given in square brackets, like this:

Does anybody know of any existing symbol that has been used for this?
