      I only ever use Scala's \u???? escapes for one thing: writing `\usepackage foo` when I embed LaTeX in multiline strings. Like this: \u005cusepackage foo Just try writing it without them... Seriously, try it.

      Any reason you're not using a string interpolation? Writing s"""\\usepackage""" works. Otherwise, you could write """⧵usepackage""".replace('⧵', '\\') where '⧵' is the reverse solidus operator :^)

      Well, I am using string interpolation... but I thought that didn't work! So I just checked, and it didn't work with Scala 2.9, but does in 2.10. My code is actually on 2.12, but my "trick" dates back over a decade... ;)

      Interestingly, '\' displays correctly on my phone, but not on my computer, which is funny... I thought Twitter upgraded to 2.10.

      Though *my* tweet shows it consistently... but yours changes!
