Bug ID: 107769
Summary: spell checking should normalize data first
Product: LibreOffice
Version: 5.4.0.0.alpha1+ Master
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Linguistic
Assignee: [email protected]
Reporter: [email protected]
Words to be spell checked should be converted to NFKC first so that spell
checking dictionaries don't need to hold all forms (NFD, NFC, mixed) of a word.
I'm going to sketch my thoughts on how to do it here in case I can't get back
to the bug for a while. Anyone want to take it further?
In SpellChecker::GetSpellFailure in lingucomponent/source/spell/sspellimpl.cxx,
rather than doing a poor man's hand created NFK into nWord, start with an nWord
created something like:
icu::UnicodeString rIn(reinterpret_case<const UChar *>(rWord.getStr()),
rWord.getLength());
icu::UnicodeString normal;
UErrorCode rCode;
icu::Normalizer(rIn, UNORM_NFKC, normal, rCode);
OUString nWord(U_SUCCESS(rCode) ? OUString(reinterpret_case<Sal_Unicode
*>(normal.getBuffer()), normal.length()) : OUString());
then use nWord instead of rWord for the rest of the function.
Need to find a test for this.
