Library: UTF-8 text processing (UTF8PAT legacy)
You can use utf8-char as a pattern to match UTF-8 encoded characters in your input data.
The following program converts a UTF-8 encoded file to a long character encoding (2 bytes for every character):
include utf8pat.xin process submit file #main-input find utf8-char => char output "2f0b" % utf8-char-number char
