While compiling a sketch with a string containing the sequence "/*", I noticed the compiler thinks this is also a start of a comment block and thus expects me to end it. Good thing the string is still compiled correctly.
Ah I didn't think about that, even if I used it in the same string earlier for escaping the quotation mark. But it didn't work, strange enough. Still the same complaint about the missing */. As a test I tried preceding it with another slash // instead of a backslash /, but the byte size became different so I'm guessing the string got longer.
