|
[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.
