将Delphi XE AnsiString转换为Fu\0308rst的转义合并变音符号到最简单的WideStringFürst中的最佳方式是什么？

What is the best way to convert a Delphi XE AnsiString containing escaped combining diacritical marks like "Fu\u0308rst" into a frienly WideString "Fürst"?

我知道这并不总是可能的所有组合，但普遍的拉丁方块应该支持，而不建立愚蠢的转换表我自己。我想这个解决方案可以在新的Characters单元中找到，但是我不明白。

I am aware of the fact that this is not always possible for all combinations, but the common Latin blocks should be supported without building silly conversion tables on my own. I guess the solution can be found somewhere in the new Characters unit, but I don't get it.

推荐答案

我想你需要在您的字符串上执行 Unicode规范化。

I think you need to perform Unicode Normalization. on your string.

我不知道Delphi XE RTL中是否有一个特定的调用来执行此操作，但WinAPI调用 NormalizeString 应该在这里帮助你，模式NormalizationKC：

I don't know if there's a specific call in Delphi XE RTL to do this, but the WinAPI call NormalizeString should help you here, with mode NormalizationKC:

NormalizationKC

NormalizationKC

Unicode归一化形式KC，兼容性组合。转换每个基础加上组合字符到规范的预设等价的和所有兼容性字符到他们的等价物。例如，结扎fi成为f + i;同样，A +¨+ fi + n变为Ä+ f + i + n。

Unicode normalization form KC, compatibility composition. Transforms each base plus combining characters to the canonical precomposed equivalent and all compatibility characters to their equivalents. For example, the ligature fi becomes f + i; similarly, A + ¨ + fi + n becomes Ä + f + i + n.
