Dear context-folks,

the unicode-character ≙ is not shown in the normal text-mode and in math-mode the hat is too big in comparison to `\mathrel{\widehat{=}}`. Is that a font problem?

The character is not available in text font, but I don't find it in lmmath-regular.otf either. You can try to ask Jacko to add this range or characters to lmmath. You may try Cambria Math for comparison. However there is a fallback mechanism available. I didn't know how it is rendered at first, but then I found the following line: stack (main,characters,id,size,0x2259,0x0003D,3,0x02227) -- \buildrel\wedge\over= The command builds the character from "logical and" (\wedge) and equal sign, but the "logical and" is definitely the wrong character to use. There is "context-defined" FE302 for wedge, but then I'm also not sure about the most suitable command to build this character. Mojca
