Hi- Suppose I'm creating a new Guile port type that is going to use NCurses primitives for input (scm_getc) and output (display). NCurses can both receive input and display output of wide characters, but, these functions operate on 32-bit wide unicode codepoints, aka UTF32.
It seems that port types are inherently 8-bit, right? So to make this work, the ports will have to store and transmit characters as UTF-8 encoded data. The 'fill_input' function will have to convert UTF-32 to UTF-8 and then cache them, passing them 1 byte at a time as requested. The 'write' function will receive data 1 byte at a time and buffer it. It will only write the character when a complete UTF-32 codepoint has been received. Sound right? Has anyone already done this sort of thing? -- Mike Gran
