This document specifies a set of Label Generation Rules (LGR) for the Polish language using a language-specific repertoire for the second level domain or domains identified above. The format of this file follows [RFC 7940]. This LGR is adapted from the “Reference LGR for the Second Level for the Polish Language” [Ref-LGR-pl-Latn], for details, see Change History below.
Standalone LGR: This LGR is designed to be used in a zone that does not cater to IDNs other than those valid under this LGR. This LGR lacks features that would allow its use in the context of another LGR in the same zone, and it may contain other features incompatible with such use.
All references converge on 35 Latin code points.
There is a an IDN table published in the IANA Repository of IDN Practices for the .pl ccTLD for the Polish language [700].
Letters documented in some references but not included:
U+00DF LATIN SMALL LETTER SHARP S
U+00E0 LATIN SMALL LETTER A WITH GRAVE
U+00E2 LATIN SMALL LETTER A WITH CIRCUMFLEX
U+00E4 LATIN SMALL LETTER A WITH DIAERESIS
U+00E5 LATIN SMALL LETTER A WITH RING ABOVE
U+00E6 LATIN SMALL LETTER AE
U+00E7 LATIN SMALL LETTER C WITH CEDILLA
U+00E8 LATIN SMALL LETTER E WITH GRAVE
U+00E9 LATIN SMALL LETTER E WITH ACUTE
U+00EA LATIN SMALL LETTER E WITH CIRCUMFLEX
U+00EB LATIN SMALL LETTER E WITH DIAERESIS
U+00EE LATIN SMALL LETTER I WITH CIRCUMFLEX
U+00EF LATIN SMALL LETTER I WITH DIAERESIS
U+00F4 LATIN SMALL LETTER O WITH CIRCUMFLEX
U+00F6 LATIN SMALL LETTER O WITH DIAERESIS
U+00F9 LATIN SMALL LETTER U WITH GRAVE
U+00FB LATIN SMALL LETTER U WITH CIRCUMFLEX
U+00FC LATIN SMALL LETTER U WITH DIAERESIS
U+00FF LATIN SMALL LETTER Y WITH DIAERESIS
U+0153 LATIN SMALL LIGATURE OE
None.
No variants are applicable when using the LGR in a standalone fashion.
As specified here, the set of in-language variants is not compatible with using this LGR in a zone with another LGR and using the Common LGR to process conflicts between labels from multiple LGRs aas described in Section 3 “Use of Multiple Reference LGRs in the Same Zone” in [Level-2-Overview].
This LGR does not define named character classes.
By default, the LGR includes the rules and actions to implement the following restrictions mandated by the IDNA protocol. They are marked with ⍟.
This LGR includes the default actions for LGRs as well as the action needed to invalidate labels with misplaced combining marks. They are marked with ⍟. For a description see [RFC 7940].
The LGR in this document has been adapted from the corresponding Reference LGR for the Second Level. The Second Level Reference LGR for the Polish Language was developed by Michel Suignard and Asmus Freytag, including input by Michael Everson, Nicholas Ostler, and Wil Tan, and based on multiple open public consultations.
Language tag has been updated.
Unicode Version has been updated.
Adopted from the Second Level Reference LGR for the Polish Language [Ref-LGR-pl-Latn] without normative changes.

In the listing of the repertoire by code point, references starting from [0] refer to the version of the Unicode Standard in which the corresponding code point was initially encoded. Other references (starting from [100]) document usage of code points. Entries in the table may have multiple source reference values. In the listing of whole label evaluation and context rules, reference [150] indicates the source for common rules. For more details, see the Table of References below.
