Basically, only use echo if you want to print preformatted / unescaped data: Any extended behavior like processing backslashes isn't portable.

I do know a few ideas but do not know if this would work in the Solaris situation you quoted.

I don't see any point fighting it when there's better alternatives though. Your solution is twice as complicated and much less efficient than just using printf once to do both jobs.
printf "\033[1mBold Text\033[0m Normal Text\n"

You're not breaking the rules, though Smilie

It's completely fine to store any ASCII character besides NULL in a variable.
