An empty box means your font lacks a Tai Tham glyph; use a font that includes the script.
Why are there two Tai Tham zeros?
Both mean zero; one is religious, the other secular.
The Tham set is used in religious writing; the Hora set is used in secular writing. Tai Tham manuscripts often pair Pali—the language of many Buddhist scriptures—with regional languages such as Northern Thai, Lao, Tai Lue, and Khün.
Tai Tham is connected with the script of the Mon people used in Haripuñjaya, an ancient Mon kingdom near present-day Lamphun, Thailand. Scholars disagree about the route: one account traces the script through that local Mon tradition, while another proposes a Mon-Burmese model from Lower Burma around 1400. By the 15th century, Tham writing was adapted for local Tai languages beyond Pali. The earliest dated Tham-script document identified is a bilingual inscription on a gold leaf from 1376; the oldest known dated Tham manuscript is a Pali copy from 1471.
This is the religious Tham numeral form; use it in the ecclesiastical register.
For secular writing, use ᪀, the Hora zero. Both signs mean 0 but belong to different sets.

Questions people ask
1Why does ᪐ show as a box on some devices?
Not every system ships a font for the Tai Tham block. Where none is installed, the character shows as an empty box; adding a font such as Noto fixes it. The character itself is still correct and copies correctly.
