. . "The close back unrounded vowel, or high back unrounded vowel, is a type of vowel sound used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is \u27E8\u026F\u27E9. Typographically a turned letter m, given its relation to the sound represented by the letter u it can be considered a u with an extra \"bowl\". The sound is sometimes referred to as \"unrounded u\".The IPA prefers terms \"close\" and \"open\" for vowels, hence the name of this article."@en . . .
