   Hello-

   How is the backtick character used in posts to indicate code and how is this different from the code markup tag?

   In a recent post mbolivar reported success using the backtick.

   However, in my recent post about a possible bug in SerialUSB.read() I was not able to get a null character (backslash zero) to appear in my post.

   I will try it again here:

   On the next line I will put (ignoring spaces) the "characters" for backtick backslash zero backtick:
   
   Let's see what appears. When I viewed the post the line was empty, and when I then I tried to edit the post I saw only the two backticks (no backslash zero).

   On the next line I will put (ignoring spaces) the "characters" for backslash zero sanwiched between opening and closing code markup tags ("lessthan"code"greaterthan" backslash zero "lessthan"/code"greaterthan":
   

   Let's see what appears. Same result. When I viewed the post the line was empty, and when I then I tried to edit the post I saw only the two backticks (no backslash zero).

   In my original post about SerialUSB.read() I tried to double up the backslashes (which works in C with printf strings, but that did not work. Let me try it again.

   On the next line I will put (ignoring spaces) the "characters" for backtick backslash backslash zero backtick:
   \

   Let's see what happens. All I see is a single backslash.

   One last attempt:

   On the next line I will put (ignoring spaces) the "characters" for backtick backslash backslash zero zero backtick:
   

   Let's see what happens.

   Success! Is there an easier way to show the backslash zero null character?

   Thanks!

   StephenFromNYC - I don't see the character with the value 0

   The best I have found is backtick single-quote backslash letter-Oh single-quote backtick
   '\O' (rubbish, but at least a place holder)

   Very puzzling. After my last post, I was able to see the "simulated" null character.

   I agree I no longer see the simulated null characters where they were before.

   Let me try it again on the next line sandwiched between [ and ]:
   [\0]
   I see the null character.

   I just logged out, returned to the forums of the home page, and viewed this topic again. I see the null char.

   I do not know how or when it disappears.

   In the near future I will use gbulmer's suggestion, and I will put a comment where the viewer should correct the code.
