Unicode Reference

Unicode related information

What it is #

Routines #

Signatures are reproduced from the documentation, including their declared return types. A routine listed here is part of the type's published interface; whether Raku++ implements it is a separate question, answered by the examples below.

method version #

method version(Unicode:)

Returns a Version object representing the Unicode version.

method NFG #

method NFG(Unicode:)

Returns a Bool indicating whether complete Normalization Form Grapheme support is available.

Examples, run three ways #

Every example below comes from the official documentation, together with the output that documentation asserts. Each was then executed by Rakudo and by Raku++ when this page was built. Where the three agree, one result is shown; where they do not, all three are — because which of them is wrong is exactly the information worth having.

class Unicode { }

Not executed: the documentation states no expected output for this example.

say Unicode.version; # OUTPUT: «v15.0␤»
Documentation
v15.0
Rakudo
v17.0
Raku++

All three differ. Needs a human.

Not yet examined. Which of these is correct has not been established — do not treat either engine as settled here.

# on MoarVM
say Unicode.NFG; # OUTPUT: «True␤»
Documentation
True
Rakudo
True
Raku++

Raku++ disagrees with both the documentation and Rakudo — a defect.

# on JVM
say Unicode.NFG; # OUTPUT: «False␤»
Documentation
False
Rakudo
True
Raku++

All three differ. Needs a human.

Not yet examined. Which of these is correct has not been established — do not treat either engine as settled here.
