Regex to match numeric and special chatacters : I need regex which matches as per below values:

1. abc123   - Do not match
2. 123      - Match
3. a123bc   - Do not match
4. a#b%c    - Match
5. 13&ab12% - Match
6. আফ্রিকার  - Do not match

In short, it matches with only numeric string and any string with special character(#,&,%). Also it do not match with any other language string.

I tried this regex but it didn't work for me.

    "^[\\D][^#&%]+$"
