[Bioc-devel] Biostrings: unicode character ("compact ellipsis") in print()/show() output (2nd attempt, rephrased)

[Ulrich Bodenhofer]

Dear colleagues,

Thanks for your replies to my message! A few more comments:

  * The issue I was reporting appeared on a Linux system
    (https://;www.r-project.org/nosvn/R.check/r-devel-linux-x86_64-debian-clang/apcluster-00check.html).
  * I agree that this is mainly a problem related to how LaTeX deals
    with unicode characters. However, to be frank, I still consider
    LaTeX-based Rnw documents (regardless of whether Sweave or knitr is
    used) an important (and still really cool) way of working with R.
    Not to be able to show/print 'XString' / 'XStringSet' objects would
    be quite a shortcoming in my humble opinion. Therefore, I would
    consider it important to be able to - optionally - switch back to a
    LaTeX-safe way of showing the ellipsis character(s).

Thanks and best regards,
Ulrich

I had a lot of problems, when trying to develop the Modstrings package vignette and I couldn't get it to work with a pdf output. The number of special characters I had to deal with were from many different alphabets and resisted my attempts (without any detailed knowledge about latex to pdf conversion) to get to the bottom of it.
