Re: [Discussion] Should All String Functions Become Multi-Byte Safe?

It seems like there's still a lot of string functions that assume that a character is a single byte, and these may actually work as expected when dealing with Latin characters, but may fail unexpectedly if a sequence is more than one byte.

PHP's strings are byte-strings containing arbitrary sequences of bytes. Unless you specifically select functions that interpret the byte-strings as something else, you get a byte-string interpretation. There is nothing unexpected about that.

Are there any use cases for PHP where **single-byte** characters are the norm?

Dealing with binary formats.

It seems that if everything on the Internet is multi-byte encoded now, then all of the PHP string functions should be multi-byte safe.

The premise is false. Everything on the Internet is byte-strings (also called "octet-string"). -------- You might be interested in https://externals.io/message/119149#119149. Best regards Tim Düsterhus
