1.48 millert 87:
1.51 millert 88: [This entry is a summary, not a precise list of changes.]
1.46 millert 89:
1.51 millert 90: Added --csv option to enable processing of comma-separated
91: values inputs. When --csv is enabled, fields are separated
92: by commas, fields may be quoted with " double quotes, fields
93: may contain embedded newlines.
1.46 millert 94:
1.51 millert 95: If no explicit separator argument is provided, split() uses
96: the setting of --csv to determine how fields are split.
1.44 millert 97:
1.51 millert 98: Strings may now contain UTF-8 code points (not necessarily
99: characters). Functions that operate on characters, like
100: length, substr, index, match, etc., use UTF-8, so the length
101: of a string of 3 emojis is 3, not 12 as it would be if bytes
102: were counted.
1.43 millert 103:
1.51 millert 104: Regular expressions are processes as UTF-8.
1.6 kstailey 105:
1.51 millert 106: Unicode literals can be written as \u followed by one
107: to eight hexadecimal digits. These may appear in strings and
108: regular expressions.
