Sep 12, 2023: Fixed a length error in u8_byte2char that set RSTART to incorrect (cannot happen) value for EOL match(str, /$/). ----------------------------------------------------------------- [This entry is a summary, not a precise list of changes.] Added --csv option to enable processing of comma-separated values inputs. When --csv is enabled, fields are separated by commas, fields may be quoted with " double quotes, fields may contain embedded newlines. If no explicit separator argument is provided, split() uses the setting of --csv to determine how fields are split. Strings may now contain UTF-8 code points (not necessarily characters). Functions that operate on characters, like length, substr, index, match, etc., use UTF-8, so the length of a string of 3 emojis is 3, not 12 as it would be if bytes were counted. Regular expressions are processed as UTF-8. Unicode literals can be written as \u followed by one to eight hexadecimal digits. These may appear in strings and regular expressions.
