/* or */ character sequence replaced during code generation

I include the character sequence /* or */ in any place in the model (Block's description for ex.), in order to be included as comment in the generated code.

In the generated code, the sequence /* is replaced with /+, and */ is replaced with +/

I'm ok with this, since the comments in the c code generation implements the comments with

/* My comment style */

My question is : Is there any place where this behaviour is documented by Mathworks ?

Thanks for your help
