Description Sébastien Wilmet 2015-12-20 13:09:31 UTC 
Try:

$ devhelp --search gtk_text_iter_forward_lines

There is only one search result, the exact link. But the search entry contains a trailing space, like this:
"gtk_text_iter_forward_lines "

I think it doesn't happen with all symbols. It looks like a g_strstrip() is needed somewhere in Devhelp, or fixing the problem at the source in GTK-Doc maybe. It anyway needs some investigation to know where the space come from.
Comment 1 Frederic Peters 2016-01-27 11:45:38 UTC 
Looking at the source .devhelp2 file it has this:

  <keyword type="function" name="gtk_text_iter_forward_line ()" link="GtkTextIter.html#gtk-text-iter-forward-line"/>

And the character before the parentheses is not an ASCII space but a non-breaking space and it's not stripped correctly.

I went the easy way and added custom handling for this precise situation. (missing a general utf-8 capable g_strstrip)
