Oracle SQL query for getting specific special characters from a table

Question

Hi all,
This is my table
Table Name- Table1
S.no    Name
1          aaaaaaaa
2          a1234sgjghb
3          a@3$%jkhkjn
4          abcd-dfghjik
5          bbvxzckvbzxcv&^%#
6          ashgweqfg/gfjwgefj////
7          sdsaf$([]:'
8          <-fdsjgbdfsg
9           dfgfdgfd"uodf
10         aaaa  bbbbz#$
11         cccc dddd-/mnm
The output has to be
S.no    Name
3          a@3$%jkhkjn
5          bbvxzckvbzxcv&^%#
7          sdsaf$([]:'
8          <-fdsjgbdfsg
10         aaaa  bbbbz#$
It has to return "Name" column which is having special characters,whereas some special chars like -, / ," and space are acceptable.
The Oracle query has to print columns having special characters excluding -,/," and space
Can anyone help me to get a SQL query for the above.
Thanks in advance.

You can achieve it in multiple ways. Here are few.
SQL> with t
  2  as
  3  (
  4  select 1 id, 'aaaaaaaa' name from dual union all
  5  select 2 id, 'a1234sgjghb' name from dual union all
  6  select 3 id, 'a@3$%jkhkjn' name from dual union all
  7  select 4 id, 'abcd-dfghjik' name from dual union all
  8  select 5 id, 'bbvxzckvbzxcv&^%#' name from dual union all
  9  select 6 id, 'ashgweqfg/gfjwgefj////' name from dual union all
10  select 7 id, 'sdsaf$([]:''' name from dual union all
11  select 8 id, '<-fdsjgbdfsg' name from dual union all
12  select 9 id, 'dfgfdgfd"uodf' name from dual union all
13  select 10 id, 'aaaa  bbbbz#$' name from dual union all
14  select 11 id, 'cccc dddd-/mnm' name from dual
15  )
16  select *
17    from t
18   where regexp_like(translate(name,'a-/" ','a'), '[^[:alnum:]]');
        ID NAME
