I am trying to find an Regex pattern for my angular application which accepts following cases

• should not contain only special character EX: {$%_^*)
• should not contain only blank spaces EX: ( )
• can accept all the languages including hindi, telgu, bangla and so on with special character. Ex: (A$যক্ষঙ্ক), (AAAA), (TEsT$^#), (কখঠডঃ)

Right now i am using ".[a-zA-Z0-9\p{L}]+.$" this regex pattern. It servers the work but not working when i pass only hindi, telgu or other language letter.

any help is appreciated. Thank you in advance
