This seems pretty reasonable, I think we were just being conservative during the initial implementation. |

In HTML5 standard, there is no restriction on what forms an ID attribute. The only reason to append a alphabet in the front of original characters is for compatibility.
As far as I know, some popular content generating services, including GitHub, GitBook and GitLab, accept a heading with non-alphabetic initial as a valid ID attribute. Maybe we can conform with the standards without appending an unexpected arbitrary character on ID. This feature will make writing much more ergonomic for non-English users.
