Constant stringsext::finding::OUTPUT_BUF_LEN

pub const OUTPUT_BUF_LEN: usize = 0x9192;

OUTPUT_BUF_LEN needs to be long enough to hold all findings that are decoded to UTF-8 in scan::scan(). To estimate the space needed to receive all decodings in UTF-8, the worst case - Asian like EUC_JP - has to be taken into consideration: Therefor, in order to avoid output buffer overflow, OUTPUT_BUF_LEN should be at least twice as big as INPUT_BUF_LEN. You can also check the minimum length with Decoder::max_utf8_buffer_length_without_replacement. Unfortunately this can not be done programmatically, because output_buffer is a statically allocated array.
