Other implementations of `printf` permit arbitrary data to be passed to `printf`. The only restriction is that a null byte terminates FORMAT and ARGUMENT argument strings (since they are C strings). The current implementation only accepts FORMAT and ARGUMENT arguments that are valid UTF-8 (this is being enforced by clap). This commit removes the UTF-8 validation by switching to OsStr and OsString. This allows users to use `printf` to transmit or reformat null-safe but not UTF-8-safe data, such as text encoded in an 8-bit text encoding. See the `non_utf_8_input` test for an example (ISO-8859-1 text). [drinkcat: also squashed in this commit to ease rebase] Author: Justin Tracey <jdt.dev@unsuspicious.click> uucore, printf: improve non-UTF-8 format arguments This fixes handling of format arguments, in part by eliminating duplicate implementations. Utilities with format arguments other than printf will no longer accept things like "'a" as numbers, etc. Co-authored-by: Justin Tracey <jdt.dev@unsuspicious.click> |
