I have a text area where the user can type some text, and after that, with function, i transform it to sentence case. The first letter is capitalized, as is the dot that follows it.
Example
input –> output
hello, one two. three four –> Hello, one two. Three four
But it works only with regular letters from a to z. But I also require characters from other languages, such as Danish Æ, Ø, Å
here is functions which wors great with letters from a to z
function sentenceCase(input, lowercaseBefore) {
input = (input === undefined || input === null) ? '' : input;
if (lowercaseBefore) { input = input.toLowerCase(); }
return input.toString().replace(/(^|\. *)([a-z])/g, function (match, separator, char) {
return separator + char.toUpperCase();
});
}
I found that there is something like this to catch another characters also [\p{L}\p{M}]
it works in regex101 (^|\. *)([\p{L}\p{M}]) but when I put it in the code, the function not showing any errors and also not working. Text is not transforming.
replace [a-z] with [\p{L}\p{M}]
>Solution :
To match any Unicode lowercase letters, you need to use \p{Ll} Unicode category/property class together with the u flag:
/(^|\. *)(\p{Ll})/gu
Now, this will match multiple occurrences of
(^|\. *)– Group 1: start of string or a.followed with zero or more regular spaces(\p{Ll})– Group 2: any Unicode lowercase letter.
