I had to use mutableCopy here because creating NSMutableAttributedString from NSString loses the information about diacritics context.

[attributedString beginEditing];

NSMutableDictionary<NSAttributedStringKey, id> *attributes = [_backedTextInputView.defaultTextAttributes mutableCopy];
[attributes removeObjectForKey:RCTTextAttributesTagAttributeName];
[attributedString addAttributes:attributes range:NSMakeRange(0, attributedString.length)];

Because of the above change, now the attributed string also contains previous styling so I need to apply default text attributes in order to reset it.

For some reason, restoring RCTTextAttributesTagAttributeName attribute also breaks the diacritics context so I need to make sure it is not applied. This can be done either by removing it from the dictionary or calling [NSAttributedString removeAttribute] later on.

This attribute is also removed by React Native itself: https://github.com/facebook/react-native/blob/f9a5b30e5a805061416123d037351e5c03860756/packages/react-native/Libraries/Text/TextInput/RCTBaseTextInputView.mm#L175-L179


// If the attributed string ends with underlined text, blurring the single-line input imprints the underline style across the whole string.
// It looks like a bug in iOS, as there is no underline style to be found in the attributed string, especially after formatting.
// This is a workaround that applies the NSUnderlineStyleNone to the string before iterating over ranges which resolves this problem.
[attributedString addAttribute:NSUnderlineStyleAttributeName value:[NSNumber numberWithInteger:NSUnderlineStyleNone] range:NSMakeRange(0, attributedString.length)];
[attributedString removeAttribute:NSUnderlineStyleAttributeName range:NSMakeRange(0, attributedString.length)];

_blockquoteRanges = [NSMutableArray new];
