I think your (unstated) editor is displaying backspaces with ^H. The Section Header convention in Rd files is with interspersed underscores so they look like:

_D_e_s_c_r_i_p_t_i_o_n:

The ^H's are apparently being put in to "erase" or squeeze together the text separated by <underscores> and your editor is not handling it in the manner expected.
