Is this a rule in english HELP please

[kazik]

Hi everyone

I'm polish, and I'm just starting my DTP carrier, recently i got a client which claims that also in enlglish DTP editing you shal mov letter "a" from an edn of a line to the beggining of the next line.

Is this a rule in engish?
Example

My name is kazik. I'm 23 years old. I have a
cat. The cat is black and anoying.

Shal i move to tthe underlined letter to the beggining of the next line? Is this a mistake in english? There is a huge quarell on polish DTP forums about this! Shal it look like this?:
