# How to make \circledR show up when using newtx?

Compile the following code with latex+dvips:

\documentclass{article}
\usepackage{newtxtext,newtxmath}
\begin{document}
\circledR $$\circledR$$
\end{document}


As a result, we get an empty document (except the page number). The compilation finishes successfully, only there is a hint in the log file:

"Missing character: There is no ò in font ntxsym!"

How to get ® in newtx in text and in math? Any (quick) bugfix? After all, the changelog of newtx says for version 1.515 this:

"Corrected definitions of [...] \circledR"

so, this character should work.

The newtx author has been e-mailed on 2019-07-11, but has not reacted as of 2019-07-17. If anyone has an e-mail address of him different from the one mentioned at CTAN, please feel free to nag him.

• The definition points to a non existent glyph. You can use \textregistered, though. – egreg Jul 11 '19 at 13:17

Apparently, the characters in slots octal 362 and 363 of the font ntxsym didn't go through and indeed, if I look at the virtual font I see

(CHARACTER O 361
(CHARWD R 0.504)
(CHARHT R 0.688499)
(CHARIC R 0.03)
(MAP
(MOVERIGHT R 0.03)
(SELECTFONT D 1)
(SETCHAR C q)
)
)
(CHARACTER O 364
(CHARWD R 0.684)
(CHARHT R 0.729)
(CHARIC R 0.03)
(MAP
(MOVERIGHT R 0.03)
(SELECTFONT D 1)
(SETCHAR C t)
)
)


The two glyphs should be the circled R and S.

You can get them from the TX fonts where they should come from anyway.

\documentclass{article}
\usepackage{newtxtext,newtxmath}

\renewcommand{\circledR}{\mbox{\usefont{U}{txsya}{m}{n}\symbol{'162}}}
\renewcommand{\circledS}{\mbox{\usefont{U}{txsya}{m}{n}\symbol{'163}}}

\begin{document}

\circledR\ \circledS

\end{document}


## UPDATE 2020

The fonts have been fixed. Now

\documentclass{article}
\usepackage{newtxtext,newtxmath}

\begin{document}

\circledR $$\circledR$$

$$\circledS$$

\end{document}


will give the expected result. Note that \circledS is defined as a math symbol, so it cannot be used in text mode.

• @MdAyq5 I proposed a workaround. Anyway, \textregistered seems even better. – egreg Jul 17 '19 at 20:07
• @user49915 The fonts have been fixed; the package author decided that \circledS is only a math symbol. – egreg Apr 30 '20 at 10:42
