Text characters that look like trees
โ is not a tree in Unicode. It is an APL functional symbol called "delta stile", from the APL programming language, where it means "grade up": it returns the order that would sort a list from smallest to largest. Its triangle on a stem just happens to look like a little pine. โ (grade down) is the same tree upside down.
โ (upwards two headed arrow) makes a great pine forest when you repeat it: โโโ. โ (upwards arrow with double stroke) looks like a fir with branches; Apple uses it as the Page Up key symbol. All three are text, so they match your font.
Tree emoji and what they mean
๐ฒ (evergreen tree) suits forests, camping and winter, ๐ณ (deciduous tree) parks, nature and family trees, ๐ด (palm tree) beaches and vacations, and ๐ต (cactus) the desert. ๐ is the Christmas tree (see the Christmas symbols), and ๐ is the tanabata tree, a bamboo branch hung with paper wishes for the Japanese star festival. ๐ชพ (leafless tree) arrived in Unicode 16.0, so older phones may not show it yet.
In Japanese and Chinese, the character for tree is ๆจ. Two trees make ๆ (woods) and three make ๆฃฎ (forest), a fun trio for nature usernames.
How to make a forest border
Repeat one tree for a clean line (โโโโ), mix shapes for a wilder forest (โ โ โ โ), or put a moon or tent in the middle. Add a peak from the mountain symbol page and you have a whole landscape in one line.
In Microsoft Word, type 234B and press Alt + X for โ. For emoji trees, search the emoji keyboard for "tree", or press Windows + . on a PC and Control + Command + Space on a Mac.
