8 arcs, 2 directions, there are a combination of 16 possibilities. Each arc can be clockwise or anti-clockwise. There are 2 of them, and 4 of the diagonal arcs. The names are inconsistent.įinally, in Unicode 7, a new one with consistent name is added. You can see that, this right pointing arrow was there first. However, there was no “RIGHTWARDS BLACK ARROW” for about 10 years. For similar reasons, other symmetric versions of the same style such as upward and or downward versions are scattered in wildly different blocks.įor example, here's some arrows and their names: Codepoint Thus you have “Supplemental Arrows-A” and “Supplemental Arrows-B”. So, the left pointing ones get added, in the same block but different neighborhood, or in another block. But later, it's realized the left pointing ones are important too, for one reason or another, and sometimes there's a need just for completeness because Unicode became more wide spread. In the beginning of Unicode history, there's just a right pointing arrow of a particular style, because left pointing ones are seldomly or never used. The most common ones are collected in “Symbols, Arrows (2190–21FF)”.
ARROW GOING LEFT RIGHT CODE
They are scattered in different code blocks. For example, → has codepoint 8594 or hexadecimal 2192. Note: each Unicode character has a ID called its “codepoint”. Also, there are a lot symmetry issues, and some mirror image isn't there. They are scattered in different places, and are hard to find. It took me several days to collect and organize these arrows. These are from several different sections of Unicode, including: Here is a screenshot showing what they look like in my browser.
