Expand description

Parses the input as a sequence of UTF-8 characters that satisfy the predicate cond. If invalid UTF-8 is encountered, it is replaced by char::REPLACEMENT_CHARACTER and parsing continues.

This function is zero-copy if the parsed input is valid UTF-8, otherwise a string gets allocated because of the need to insert replacement characters. This is similar to how String::from_utf8_lossy works.
