Using \textregistered{} and/or \textregistered result in ®; ®;

Is there a way I can redefine this symbol so that it doesn't include a semicolon or is there a package conflict that is causing this problem?

I had to redefine \textrademark in an if statement because it wasn't working \renewcommand{\texttrademark}{{\si{^{TM}}}} so I am concerned of a compatibility problem somewhere. Not quite sure what the offending package is however since the way I understand it, numerous packages redefine and avail a user of font and symbol controls.

This is a bug in tex4ht, \textregistered is defined like this in html4.4ht:


this may seem little bit cryptic, but \special{t4ht@+\string&{35}xAE{59}} outputs special instruction to replace letter x with html entity ®, this html entity is in later process translated to ® character. there is unnecessary ; character. to fix this, put this into the preamble:


I posted a bug report with a patch to tex4ht bug db, so I hope it will be fixed quickly in TeXLive:

  • Interestingly I can't seem to overwrite \textregistered. I am sure the code you posted should work, but even using \renewcommand{\textregistered}{^{\si{R}}} (which is similar to how I fixed TM doesn't change anything.

    @EngBIRD maybe you use some package which redefines \textregistered? try to put that definition after begin{document}`

  • Great thanks! I usually put these sort of new commands in a tex document called immediately before the \begin{document} Turns out that wasn't enough. As per your suggestion, placing it inside \begin{document} fixed it right up.
