You can add the u flag for Unicode support. That way you can specify patterns that include character properties, such as \p{N} for numbers in any language (Arabic, Chinese, ...).

const str = 'क्या आप क्लोज़अप करते हैं ';

console.log('Letters and accent marks: ' + str.match(/^[\p{L}\p{M}]+/u))
console.log('Anything but space: ' + str.match(/^[^\p{Zs}]+/u))

Result:

Letters and accent marks: क्या
Anything but space: क्या

Explanation:

• both regex use ^ to anchor at the beginning
• regex 1: [\p{L}\p{M}]+ - one or more letters and accent marks
• regex 2: [^\p{Zs}]+ - anything that is not a space (includes all Unicode spaces)
• the u flag enables Unicode so that you can use \p{...} Unicode patterns
