Search string contains diaeresis but with source string they have same letters with different char lengths but substring is normalized in source. + 1. Search string contains diacritic and has same normalization form as in source string. + 2. Search string contains diacritic but with source string they have same letters with different char lengths but substring is normalized in source. a. search string `normalizing to form C` is substring of source string. example: search string: `U\u0308` source string: `Source is \u00DC` => matchLength is 1 b. search string `normalizing to form D` is substring of source string. example: search string: `\u00FC` source string: `Source is \u0075\u0308` => matchLength is 2 Not covered case: - - Search string contains diacritics and with source string they have same letters with different char lengths but substring is not - normalized in source. example: search string: `U\u0308 and \u00FC` (Ü and ü) source string: `Source is \u00DC and \u0075\u0308` (Source is Ü and ü) + Source string's intended substring match containing characters of mixed composition forms cannot be matched by 2. because partial precomposition/decomposition is not performed. example: search string: `U\u0308 and \u00FC` (Ü and ü) source string: `Source is \u00DC and \u0075\u0308` (Source is Ü and ü) as it is visible from example normalizaing search string to form C or D will not help to find substring in source string. - `IgnoreSymbols` diff --git a/src/libraries/Common/src/Interop/Interop.Collation.OSX.cs b/src/libraries/Common/src/Interop/Interop.Collation.OSX.cs index eefd019055b9bf..70e907efa68a10 100644 --- a/src/libraries/Common/src/Interop/Interop.Collation.OSX.cs +++ b/src/libraries/Common/src/Interop/Interop.Collation.OSX.cs @@ -8,6 +8,12 @@ internal static partial class Interop { + internal struct Range + { + public int Location; + public int Length; + } + internal static partial class Globalization { [LibraryImport(Libraries.GlobalizationNative, EntryPoint = "GlobalizationNative_CompareStringNative", StringMarshalling = StringMarshalling.Utf16)] @@ -18,7 +24,7 @@ internal static partial class Globalization internal static unsafe partial int EndsWithNative(string localeName, int lNameLen, char* target, int cwTargetLength, char* source, int cwSourceLength, CompareOptions options); [LibraryImport(Libraries.GlobalizationNative, EntryPoint = "GlobalizationNative_IndexOfNative", StringMarshalling = StringMarshalling.Utf16)] - internal static unsafe partial NSRange IndexOfNative(string localeName, int lNameLen, char* target, int cwTargetLength, char* pSource, int cwSourceLength, CompareOptions options, [MarshalAs(UnmanagedType.Bool)] bool fromBeginning); + internal static unsafe partial Range IndexOfNative(string localeName, int lNameLen, char* target, int cwTargetLength, char* pSource, int cwSourceLength, CompareOptions options, [MarshalAs(UnmanagedType.Bool)] bool fromBeginning); [LibraryImport(Libraries.GlobalizationNative, EntryPoint = "GlobalizationNative_StartsWithNative", StringMarshalling = StringMarshalling.Utf16)] [MethodImpl(MethodImplOptions.NoInlining)] diff --git a/src/libraries/Common/src/Interop/OSX/NSRange.cs b/src/libraries/Common/src/Interop/OSX/NSRange.cs deleted file mode 100644 index ae2ad086df6da6..00000000000000 --- a/src/libraries/Common/src/Interop/OSX/NSRange.cs +++ /dev/null @@ -1,11 +0,0 @@ -// Licensed to the .NET Foundation under one or more agreements. -// The .NET Foundation licenses this file to you under the MIT license. -using System.Runtime.InteropServices; -namespace System.Globalization -{ - internal struct NSRange - { - public int Location; - public int Length; - } -} diff --git a/src/libraries/System.Globalization/tests/CompareInfo/CompareInfoTests.IsSuffix.cs b/src/libraries/System.Globalization/tests/CompareInfo/CompareInfoTests.IsSuffix.cs index 34b11fa9c43c27..8b83094efe3be8 100644 --- a/src/libraries/System.Globalization/tests/CompareInfo/CompareInfoTests.IsSuffix.cs +++ b/src/libraries/System.Globalization/tests/CompareInfo/CompareInfoTests.IsSuffix.cs @@ -107,7 +107,7 @@ public static IEnumerable IsSuffix_TestData() { yield return new object[] { s_hungarianCompare, "foobardzsdzs", "rddzs", CompareOptions.None, false, 0 }; yield return new object[] { s_frenchCompare, "\u0153", "oe", CompareOptions.None, false, 0 }; - if (!PlatformDetection.IsHybridGlobalizationOnOSX) // TODO: check this for OSX + if (!PlatformDetection.IsHybridGlobalizationOnOSX) { yield return new object[] { s_invariantCompare, "\uD800\uDC00", "\uDC00", CompareOptions.None, false, 0 }; yield return new object[] { s_invariantCompare, "\uD800\uDC00", "\uDC00", CompareOptions.IgnoreCase, false, 0 }; diff --git a/src/libraries/System.Private.CoreLib/src/Resources/Strings.resx b/src/libraries/System.Private.CoreLib/src/Resources/Strings.resx index dbc8fca4de5679..573e64dadfdfc1 100644 --- a/src/libraries/System.Private.CoreLib/src/Resources/Strings.resx +++ b/src/libraries/System.Private.CoreLib/src/Resources/Strings.resx @@ -4064,6 +4064,9 @@ CompareOptions = {0} are not supported when HybridGlobalization=true on this platform.
