BibTeX, biblatex and biber ⇒ Underscore in URL

[esong_98]

I am constructing in TXC a reference list in a file called Mybib.bib. For the most part, the references are showing up fine in the output without error, except for references that have an underscore in the url. Specifically, I have been using this code:

Code: Select all

@unpublished{Bayraktar11,
        author = " Bayraktar, Erhan ... ",
        title = "Minimizing the Probability of...",
        note = "preprint (2011), available at 
        \texttt{http://www.academia.edu/275940/Minimizing_the_Lifetime_Shortfall_or_Shortfall_at_Death}"
}

Unfortunately, the program makes the next letter after the underscore a subscript - although the formatting is otherwise correct and doesn't run off the page in the output. I've tried to solve this problem by making all underscores \_. Unfortunately, the computer doesn't like this, too and that just makes the compiler quit before the references can be printed. I've also tried putting this in my preamble after the \usepackage{setspace} shown below:

Code: Select all

\usepackage{url}

Then I type:

Code: Select all

@unpublished{Bayraktar11,
        author = " Bayraktar, Erhan ... ",
        title = "Minimizing the Probability of...",
        note = "preprint (2011), available at 
        \url{\texttt{http://www.academia.edu/275940/Minimizing_the_Lifetime_Shortfall_or_Shortfall_at_Death}}"
}

This solves the problem of printing the underscore correctly, but now the citation runs off the page in the output and the font and style is off.

Does anyone have any other ideas? I could just drop the citation since this is an unpublished manuscript. But I would still like to see a solution offered for future purposes.

By the way, my preamble looks like this (if it helps):

Remove \texttt{} within \url. The latter already produces typewriter text. URLs will be broken at certain places, not all places are allowed to keep it readable, because a link should be exact. See url manual. Where should a breakpoint be?

I had this problem and solved it. The bib file that my reference manager created substituted {\_} whenever it saw an underscore. So Missing_Link became Missing{\_}Link. Latex didn't like this and ruined my bibliography - it inserted a 7B%5C_%7D string instead.

My solution was to run a bash script on the bib file before I ran Latex; the script contained this line:

Code: Select all

sed -i 's/{\\_}/_/g' library.bib

Where my bib file was called library.bib. This removed the {\_} and replaced with an underscore.

My reference manager (Mendeley) would overwrite the bib file with the erroneous version everytime it ran, but this wasn't a problem as I had automated the process of running the bash script (I ran it from within vim and it also did some other functions like backing up the previous version and running a word count).

Hope this helps. Eight years too late mind you...
