The same happened to my use-case. I have been using markdown which i have later on truncated and it turns out that markdown processing left some new lines in HTML code which in turn truncate_html deleted.

I am currently working on a workaround...

I figured out what it was: non-breaking spaces (unicode 160). See http://www.rubyinside.com/the-split-is-not-enough-whitespace-shenigans-for-rubyists-5980.html

They are removed instead of being treated like regular spaces.

Handle whitespace more generically
458ab10 
This fixes the issue of non-breaking spaces being discarded, resulting in words being joined together. `\s` and `\S` only match on space (character 32). HTML often uses non-breaking spaces (character 160). A more general approach is to use `[[:space:]]` instead. According to the `Regexp` documentation, `[[:space:]]` matches "Whitespace character ([:blank:], newline, carriage return, etc.)"

Fixes hgmnz#68
