Can't use underscore in \author{}

[anjiro]

Example:

\author{%
  \alignauthor{Leave Authors Anonymous\\
    \affaddr{for Submission}\\
    \affaddr{City, Country}\\
    \email{hello\textunderscore friend@myinst.edu}}\\

Yields

Same results with \_.

[ayman]

hmm...can you report back what this does:

\href{mailto:hello_friend@myinst.edu}{hello\_friend@myinst.edu}

will require the hyperref package.

[anjiro]

Same thing:

[ayman]

Ok - will investigate...open to suggestions.

[anjiro]

I think it might be a font thing. There are a lot of font things going on the .cls file that I don't understand.

I've run into this in the past too. As it only occurs in email addresses, I ended up just using the solution found here (http://tex.stackexchange.com/a/48633):

\texttt{\char`_}

Until all these little bugs are worked out, maybe there's a case for a "known issues" page for all these templates? (or the GitHub wiki pages).

[ayman]

That's (Wiki/Known Issues) a neat idea...i'll try to set it up soon. If @anjiro confirms you're solution we can close this issue.

[anjiro]

Ok, I poked at this a little more. The issue is in line 439 of the .cls file, where we have

\newfont{\eaddfnt}{ptmr7t at 12pt}                    % 05-16-2006 atd

I think it's due to the use of a 7-bit font; changing the 7 to 8 makes an (escaped) underscore work properly. I don't know what (if any) implications there are to doing this. Changing all of the 7ts to 8t causes no issues with my modern install of MacTeX.

[simonrob]

Nice find! No problems here either when changing all 7-bit fonts in that section to 8-bit.

As an aside, this also fixes a related issue where accented characters (e.g., àéîö etc) didn't work in author names. Probably well worth making this change.

[ayman]

Wow. Thanks everyone. So I dug back into the standard ACM template and found the 8-bit fonts were added in 2006.

\newfont{\secfnt}{ptmb8t at 12pt}
\newfont{\secit}{ptmbi8t at 12pt}    %13 Jan 00 gkmt
...

So I think we should take this merge too.

[ayman]

@anjiro do you have a pull-request for me here?

[anjiro]

No, because I'm not familiar enough with Metafont to know how changing from
7- to 8-bit fonts might affect things. I was hoping you knew!

Nope...but here's the whole block from the ACM template:

\ifnum\ACM@basesize=9\relax
\newfont{\secfnt}{ptmb8t at 12pt}
\newfont{\secit}{ptmbi8t at 12pt}    %13 Jan 00 gkmt

\newfont{\confname}{ptmri8t at 8pt}
\newfont{\crnotice}{ptmr8t at 8pt}
\newfont{\ninept}{ptmr8t at 9pt}
\fi
\ifnum\ACM@basesize=10\relax
\newfont{\secfnt}{ptmb8t at 13pt}
\newfont{\secit}{ptmbi8t at 13pt}    %13 Jan 00 gkmt
\newfont{\subsecfnt}{ptmri8t at 12pt}
\newfont{\subsecit}{ptmbi8t at 12pt}  % 
\newfont{\ttlfnt}{phvb8t at 20pt}
\newfont{\ttlit}{phvbo8t at 20pt}    % GM 2/4/2000
\newfont{\subttlfnt}{phvr8t at 15pt}
\newfont{\subttlit}{phvro8t at 15pt} % GM 2/4/2000
\newfont{\subttlbf}{phvb8t at 15pt}  % 13 Jan 00 gkmt
\newfont{\aufnt}{phvr8t at 12pt}
\newfont{\auit}{phvro8t at 12pt}     % GM 2/4/2000
\newfont{\affaddr}{phvr8t at 11pt}
\newfont{\affaddrit}{phvro8t at 11pt} % GM 2/4/2000
\newfont{\eaddfnt}{phvr8t at 12pt}
\newfont{\ixpt}{ptmr8t at 10pt}
\newfont{\confname}{ptmri8t at 9pt}
\newfont{\crnotice}{ptmr8t at 9pt}
\newfont{\ninept}{ptmr8t at 10pt}
\fi

So it might just be changing 7s to 8s.
