utf8accents.sty  already does this; viz.

[GlenLivet:~/Documents/TeX_Documents] rossmoor% grep textascii 
test/utf8accents.sty
%\DeclareUTFcharacter[\UTFencname]{x005E}{\textasciicircum}% see x02C6
%\DeclareUTFcharacter[\UTFencname]{x0060}{\textasciigrave}% see x02CB
%\DeclareUTFcharacter[\UTFencname]{x007E}{\textasciitilde}% see x02DC
\DeclareUTFcharacter[\UTFencname]{x00A8}{\textasciidieresis}
%\DeclareUTFcharacter[\UTFencname]{x00AF}{\textasciimacron}% see x02C9
%\DeclareUTFcharacter[\UTFencname]{x00B4}{\textasciiacute}% see x02CA
%\DeclareUTFcharacter[\UTFencname]{x00B8}{\textasciicedilla}% see x02DB
\DeclareUTFcharacter[\UTFencname]{x02C6}{\textasciicircum}
\DeclareUTFcharacter[\UTFencname]{x02C7}{\textasciicaron}
\DeclareUTFcharacter[\UTFencname]{x02C9}{\textasciimacron}
\DeclareUTFcharacter[\UTFencname]{x02CA}{\textasciiacute}
\DeclareUTFcharacter[\UTFencname]{x02CB}{\textasciigrave}
\DeclareUTFcharacter[\UTFencname]{x02D8}{\textasciibreve}
\DeclareUTFcharacter[\UTFencname]{x02DB}{\textasciicedilla}
\DeclareUTFcharacter[\UTFencname]{x02DC}{\textasciitilde}
%\DeclareUTFcharacter[\UTFencname]{x????}{\textasciidieresis}% see x00A8


So you should get the right characters automatically.
However, if you have loaded  textcomp.sty  *after* utf8accents,
then this may shadow the above declarations.
(Best is to not load the textcomp  package.
With  utf8accents  you shouldn't need it.
Similarly do not load other packages, such as  inputenc .)

However...

  ... the Ux02DC code-point for  \textasciitilde  may be wrong.
It's correct for the tilde-accent character, but you seem to
want a non-accent tilde.

You can get this with:

\DeclareUTFcharacter[\UTFencname]{x007E}{\textasciitilde}% see x02DC

Similarly for the other characters:
   ...circum  ...grave  ...acute  ...macron  ...cedilla


Should the  \textascii...  macros for these be in the  Ux00..  range ?
Or should they be the accent characters in the  Ux02..  range ?


Cheers,

	Ross
