我怎样才能在Google表格中统一/表示Unicode字符？

问题描述

我试图为Google表格编写一个公式，它将Unicode字符与变音符号转换为它们的纯ASCII等效字符。 我看到。

我试图编写一个公式（类似于）：

  REGEXREPLACE（público，（\pL）\ pM *，$ 1）
  

但表格产生以下错误：

我想我可以写一个由一组嵌套的SUBSTITUTE函数组成的公式（），但这似乎相当可怕。

任何人都可以提供一个更好的方法来标准化Google表格中带有变音符号/重音符号的Unicode字母的建议公式？

[<：^ alpha：]] （取反的ASCII字符类）适用于 REGEXEXTRACT 公式。

但是 = REGEXREPLACE（público，（[[：alpha：]]）[[[ ：^ alpha：]]，$ 1）结果为pblic。所以，我想，公式不知道确切的ASCII字符必须替换ú。

解决方法 取词públicē;我们需要替换它中的两个符号。把这个单词放在单元格A1中，并在B1单元格中输入这个公式：

  = JOIN（，ArrayFormula（IFERROR（VLOOKUP SPLIT（REGEXREPLACE（A1， $ 1  - ），  - ， （）。），d：（ （） REGEXREPLACE（A1， $ 1-）E，2,0），SPLIT，  - ））））
  

然后在范围D：E中创建替换目录： p>

  DE 
 1 u 
 2 $ e 
 3 ... 
  

这个公式仍然很丑陋，但更有用，因为您可以通过向表中添加更多字符来控制您的目录。

或者使用Java Script

另外，它可以在谷歌工作表中使用。

I'm trying to write a formula for Google Sheets which will convert Unicode characters with diacritics to their plain ASCII equivalents.

I see that Google uses RE2 in its "REGEXREPLACE" function. And I see that RE2 offers Unicode character classes.

I tried to write a formula (similar to this one):

REGEXREPLACE("público","(\pL)\pM*","$1")

But Sheets produces the following error:

I suppose I could write a formula consisting of a long set of nested SUBSTITUTE functions (Like this one), but that seems pretty awful.

Can any offer a suggestion for a better way to normalize Unicode letters with diacritical/accent marks in a Google Sheets formula?

解决方案

[[:^alpha:]] (negated ASCII character class) works fine for REGEXEXTRACT formula.

But =REGEXREPLACE("público","([[:alpha:]])[[:^alpha:]]","$1") gives "pblic" as a result. So, I guess, formula doesn't know what exact ASCII character must replace "ú".

Workaround

Let's take the word públicē; we need to replace two symbols in it. Put this word in cell A1, and this formula in cell B1:

=JOIN("",ArrayFormula(IFERROR(VLOOKUP(SPLIT(REGEXREPLACE(A1,"(.)","$1-"),"-"),D:E,2,0),SPLIT(REGEXREPLACE(A1,"(.)","$1-"),"-"))))

And then make directory of replacements in range D:E:

    D    E
1   ú   u
2   ē   e
3  ...  ...

This formula is still ugly, but more useful because you can control your directory by adding more characters to the table.

Also found a good solution, which works in google sheets.
