This is not a bug itself, but it's a problem that I run into often because I develop unicode applications with mbstring overloading functions.
Whenever I try to know the length of binary information (for example, a lob retrieved from the database, in order to set the content-length header) I get errors because raw bytes inside the variable are interpreted as unicode escape sequences. So the length returned by strlen is less than the correct one.
See Bug #35412 for a similar situation (there might be more).
In that cases I use mb_strlen($str, 'ASCII') but it would be nice to have a function called bytecount or something like that.
Maybe there are already plans for this in PHP6 with the new unicode thing.

I could send a patch with a sinonym for the not overloaded strlen function.... My two cents (and three lines :o) )

Thanks in advance.

This is definitely something for PHP 6 and its Unicode support.
