In most cases I have copied directly from the CF editor. Sometimes
I have copied to the application, Notepad++, from the CF editor and made some changes and then copied from Notepad++ into the forum.
Today, I cannot create the issue by copying into the forum message editor from either the CF editor or from Notepad++.
What I can do is to replace the tabs with spaces using Notepad++ and this will allow me to retain a hint of the formatting that use for writing TBASIC CFs.
I won't worry this odd behavior any more. It just was unusual that old posts started coming up with odd characters days of years after they were created.
Tanks for giving it a look.
Best regards,
