take a look at what i found:

/etc/nagios/nagios.cfg:illegal_macro_output_chars=3D`~$&|'"<>

also, in the nagios source, it strips out any ascii characters greater
than decimal 166:

                        /* illegal ASCII characters */
                        if(ch<32 || ch=3D=3D127)
                                continue;

                        /* illegal extended ASCII characters */
                        if(ch>=3D166)
                                continue;

                        /* illegal user-specified characters */
                        illegal_char=3DFALSE;
                        if(illegal_output_chars!=3DNULL){
                                for(z=3D0;illegal_output_chars[z]!=3D'\x0';=
z++){
                                        if(ch=3D=3D(int)illegal_output_char=
s[z]){
                                                illegal_char=3DTRUE;
                                                break;
                                                }
                                        }
                                }

so this is in fact by design.  can you verify that changing
the mentioned variable gets it to stop eating those special chars?

if this does solve the initial problem i'll lower the severity of
this to "wishlist" and forward a request upstream to the nagios folks
asking to provide a way to allow the high ascii chars.
