The function utf8.encoding
converts an integer
containing a Unicode character code to a
string
of bytes containing the UTF-8 encoding of that character code.
If the argument invalid-code-points
is unspecified (or specified as not-allowed
, which is the default value), invalid values will
cause utf8.encoding
to return the UTF-8 encoding of U+FFFD (which happens to be 0xEFBFBD). If the argument is specified as
not-allowed-with-throw
, invalid values will cause utf8.encoding
to throw to utf8.invalid-code-point
. If the argument is specified as allowed
the result may not be valid UTF-8.
The following program converts a long character encoding (2 bytes per character) to a UTF-8 encoding:
import "omutf8.xmd" prefixed by utf8. process submit #main-input find any{2} => char output utf8.encoding of binary char
