But in my testing, I do see an "Invalid character" message. Could you please show an example of using this new function to produce this special ``character that couldn't be interpreted''? > My feeling is that the syntax should be close in its behaviour to what the > coding systems do, and when the coding systems see a code point that is > valid but that they can't interpret, they trash the user's data. This function is not about coding systems, it's about character sets. Coding systems already replace unsupported characters with `?' (other applications behave like that as well), so perhaps we should use some more conventional character here. Does anyone have an opinion?
