Curious enough, I can't reproduce this on Alpine. (In reply to Michał Górny from comment #2) > Curious enough, I can't reproduce this on Alpine. Scratch that, I needed to install zbar library. Confirmed that segno produces identical QRCode on glibc and musl. However, `zbarimg` decodes it differently: # zbarimg --raw /tmp/dist/test.png M酺chenb𡡷her scanned 1 barcode symbols from 1 images in 0 seconds while on glibc: $ zbarimg --raw test.png Märchenbücher scanned 1 barcode symbols from 1 images in 0 seconds So apparently segno is encoding the string as iso-8859-1 but zbar is decoding it as utf-8. Incorrect. It's actually trying to decode it as big5. For some reason, iconv() for this fails on glibc: $ iconv -f utf8 -t iso-8859-1 <<<'Märchenbücher' | iconv -f big5 -t utf8 M酺chenbiconv: illegal input sequence at position 8 but passes on musl: $ iconv -f utf8 -t iso-8859-1 <<<'Märchenbücher' | iconv -f big5 -t utf8 M酺chenb𡡷her Am I the only person thinking musl upstream will tell me that POSIX technically permits that? Ok, it doesn't really matter. zbar is making horribly wrong assumptions here, and it's just a miraculous coincidence that "Märchenbücher" doesn't work on glibc. "Märchen" alone would get miscoded either way.
