terminology - What to call the phenomenon where a rectangle is shown because a font is missing a glyph


Is there a name to describe the situation where a particular character is shown on a computer screen in a particular font, but this font does not have a glyph for this particular character?


Usually, the result looks like this: □
A kind of empty rectangle. Sometimes it shows the code for that character within the rectangle.


tofubake


How do yo call this phenomenon in Japanese?

If there is no name, is there a common term referring to this "missing glyph square" in Japanese?


(It is not 文字化け. 文字化け happens when character encoding meta-information is lost. It is not the problem here. Using a better font solves this phenomenon, but does not solve 文字化け. Selecting a character encoding solves 文字化け, but does not solve this phenomenon.)



Answer



As far as Internet slang goes, the word 豆腐{とうふ} is often used as a term for replacement glyphs because of their rectangular shapes, and 豆腐[化]{ば}け or 豆腐[化]{か} describe the phenomenon in one word.




  • 画面上の日本語がすべて豆腐になってしまっていて読めない

  • フォント設定を変更しても豆腐化けが直らない
