Let me explain, I want the regular expression to \wfind the characters [a-zA-Z_0-9áéíóúüñÁÉÍÓÚÜÑ]that, as you know, are part of what is considered a word in the Spanish language.
I thought it depended on the locale, but it doesn't, since even changing the CurrentCulture before executing the regular expression, it still doesn't give me the results with accented letters.
Thread.CurrentThread.CurrentCulture = New CultureInfo("es-ES")
I have also used the alternative \p{L}with the same result.
I have looked at the options that can be put when executing regular expressions in .NET and there is one called RegexOptions.CultureInvariant, but it does not work for me because it is intended for case-sensitive string comparisons.

I could use an ad-hoc expression [a-zA-Z_0-9áéíóúüñÁÉÍÓÚÜÑ], but it's longer, less readable, and I want to support more languages in the future so I'd have to create a different one for each language.
What I am asking is if .NET has a list of languages with the characters that are part of a word and only passing the locale for example "es-ES" would already interpret \wor \p{L}as[a-zA-Z_0-9áéíóúüñÁÉÍÓÚÜÑ]
