How to use Unicode numeric values in regexprep?
显示 更早的评论
How can "Häagen-Dasz" be converted to "Haagen-Dasz" using Uincode numeric values? For example,
regexprep('Häagen-Dasz','ä','A')
works fine, but
regexprep('Häagen-Dasz','\x{C4}','a')
does not. Here, the hexadecimal \x{C4} stands for [latin capital letter a] with diaeresis, i.e. [ä].

Hi Vlad,
'\x{C4}' represents the Unicode character Ä (Latin Capital Letter A with Diaeresis) in hexadecimal notation.
If you want to replace ä (Latin Small Letter A with Diaeresis), you should use \x{E4}, which is its Unicode hexadecimal representation.
In the context of your question, you're looking to replace ä with a. The correct approach would be to use the Unicode numeric value for ä in the regex and replace it with a. Here is the code:
regexprep('Häagen-Dasz','\x{E4}','a')
Hope this helps!

inp = 'Häagen-Dasz';
baz = @(v)char(v(1)); % only need the first decomposed character.
out = arrayfun(@(c)baz(py.unicodedata.normalize('NFKD',c)),inp) % remove diacritics.
