Is there any way to keep the byte semantics (in oppose to unicode semantics) only for the existing functions? For example, the Oracle 8 functions can be configured to use utf-8 for the character encoding of strings. In order for them to work properly, fundamental functions, which Oracle 8 function call, have to behave in byte samentics. And if they work properly when the unicode semantics switch is turned on, by setting the runtime_encoding to utf-8, they can be called by uncode applications.

I couldn't parse this on the first try. Could you restate this?

Say there is a function which calls strlen($s) expecting it returns byte size of $s, and it is working fine when $s constains multibyte characters. For example, the function expects strlen('áéí') returns 6 when the encoding is utf-8. If this function is called by Uniocde ready applications on Unicode-enabled PHP, it will fall into error because strlen('áéí') will return 3. Is there any way to let strlen('áéí') return 6 only when it is called by the existing function? Hope I explained well this time. Makoto
