Add Non-Dotted / Non-Slashed Version of Zero

[abhishek-junghare]

The dotted or slashed zero (0) feels unnecessary in certain contexts and instead reduces readability.

Use Cases:

1. Color HEX Codes:
HEX codes consist of A-F and 0-9, with no potential for confusion with the letter O. A plain zero would be better for readability in this case.

2. Numeric-Only Text
In contexts like prices or telephone numbers, a plain zero provides cleaner and more intuitive readability.

Proposed Solution:
Providing a plain zero as a stylistic alternate to enhance clarity and user experience.
