AFAIK, WebAssembly requires all data to be aligned by at least the word size. This can be a problem ...

Even char? Like you cannot do char *s = ...; *s++?

Probably, you can do that. Last time I had to deal with compiling C++ to Web was, probably, ~5 years ago. And that was Emscripten.
The only thing I remember for sure I had to properly align unaligned data structures, otherwise we were getting runtime exceptions. Part of the code had to be disabled because of problems with data alignment.

This was ~FIVE years ago. Life has changed since that time. And we have WebAssembly in addition to Emscripten now.

Another thing: compilation with Emscripten wasn't a problem at all.

P.S. I personally would prefer to use Turtle because of security reasons. WebAssembly can be easily decompiled, and in case of Turtle the only thing people can steal is a picture in a Web-browser. Rolling Eyes
