Line 1,130:
<lang tcl>fconfigure $channel -buffersize $byteCount</lang>
When the channel is only being accessed from Tcl (or via Tcl's C API) it is not normally necessary to adjust this option.

var offset = 0
var char = "" // stores each byte read till we have a complete UTF encoded character
while(true) {
var b = file.readBytes(1, offset)
if (b == "") return // end of stream
char = char + b
if (char.codePoints[0] >= 0) { // a UTF encoded character is complete
System.write(char) // print it
char = "" // reset store
}
offset = offset + 1
