I recommend this change because sometimes a “-” for a bullet is confused with a minus sign, a dash (as punctuation) or many other text editing uses of “-” whereas a dot is not normally used in text (at least not frequently in English writing).
I realized that all unordered lists in this forum are marked in dots (writing in Markdown).
- Unordered item 1;
- Unordered item 2;
- Unordered item 3.
