What ʊ means
It marks a near-close, near-back rounded vowel. English dictionaries use it in words such as good and could, and pronunciation guides place it in the FOOT set, including foot and put.
Do not read it as a normal alphabetic u. The International Phonetic Association places ʊ among near-close vowels and uses the right-hand member of a vowel pair for the rounded sound.
The exact vowel quality depends on the language and accent. Treat ʊ as a pronunciation instruction, not as a letter to pronounce by its shape.
How do I type ʊ?
Use an IPA keyboard or character picker. An online IPA keyboard lets you select ʊ directly and move it into a document or message; copy it from the palette above for one-off use.
For repeated transcription, install a Unicode IPA layout or use an IPA-aware editor. Ordinary keyboard layouts usually do not provide this character as a dedicated key.
If the symbol appears as a square, question-mark box, or blank space, the text may be valid while the receiving font lacks the glyph.
Technical and academic: using ʊ signals pronunciation work, language learning, or phonetic transcription.
Do not substitute it for the long vowel uː without checking the word and accent.

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.
