Delphi XE AnsiStrings与转义的组合变音符号 [英] Delphi XE AnsiStrings with escaped combining diacritical marks

问题描述

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.
