I use TexClipse for (most) of my $latex \LaTeX$ editing, ViM otherwise.
I use Xelatex / pdflatex for project building.
These don’t always work so well together.
One issue I came across was that Mendeley can insert some weird Unicode whitespace characters that ‘disappear’ in TexClipse / Vim, but break xelatex/pdflatex.
Easy solution: set the project encoding in TexClipse to ignore these characters upon pasting.
Right click on your project -> Properties - > set Text File Encoding to US-ASCII; Apply
Job Done; No more Unicode woes!
