What 便 means
The language and surrounding word determine its meaning. Mandarin biàn covers convenience, suitability, “then,” and bodily waste; pián appears in 便宜, meaning cheap. Japanese ben appears in convenience words but also means stool; bin appears in postal and transport words. The Japanese reading tayori (たより) can mean news or a letter.
Where does 便 come from?
It evolved in Chinese writing, not as a modern icon. Its history includes seal script, an ancient Chinese writing style, and later clerical forms used by scribes. The Eastern Han dictionary Shuowen explains it through a person and changing what is unsuitable: a traditional account of making things convenient, not proof of its original purpose.
Japanese developed transport and letter senses from convenience. Around the Meiji period, an era of Japanese modernization, ben and bin became more specialized: 郵便 reinforced bin for mail, while 便利 retained ben for convenience. The excrement sense has an uncertain origin; the character is not a literal bathroom picture.
Can I send 便 by itself?
Use the whole word unless the context is clear. If someone sends only 便, ask for the full sentence and the language. A possible bathroom meaning does not establish that they intended an insult.
Ordinary vocabulary in compound words, including clinical bathroom terms—not inherently rude.
Do not use bare 便 as a “convenient” label: it can also suggest stool.

1Why does 便 show as a box on some devices?
Because that device's fonts have no glyph for it. The character is still correct and still copies correctly — the box is a missing glyph, not a broken character.
