Interesting little discrepancy -- I just found that consecutive spaces in
markup strings render correctly using the PDF backend, but get collapsed down
to one space in SVG.
I'm documenting a live-coding library, mainly using Emacs org-mode + LaTeX, but
I threw in a bit of LilyPond to make a figure showing how the text notation of
rhythm translates into notated rhythms. Laying out the table was pretty easy. I
didn't want to mess around with trying to find the exact page size by numbers,
so I rendered to SVG and opened it in Inkscape (since it has an automatic "crop
to contents" feature). Then I saw:
Source: \line { 7. \typewriter "\"--| - |- --| -\"" }
PDF view: 7. "--| - |- --| -"
SVG view: 7. "--| - |- --| -"
Whitespace is significant as a timing placeholder, so this was not acceptable.
I tried non-breaking spaces; same result. Eventually I worked around it by
inserting a zero-width space (U+200B) in between two regular spaces.
https://code.google.com/p/lilypond/issues/detail?id=1434 seems related, though
it says it's for leading and trailing spaces. If in fact it's the same issue,
probably the description to be updated to mention multiple consecutive spaces
in the middle of a string.
