Can't import UR from bc-seedtool

[ChristopherA]

From Mac Big Sur 11.1, using https://github.com/blockchaincommons.com/bc-seedtool:

% seedtool --ur | tr '[:lower:]' '[:upper:]' | tee /dev/tty | qrencode -o seedqrcode.png -l L
UR:CRYPTO-SEED/OYADGDFNLDDNPEHFSBTYTTKNIYTLDSSSDYFGLEIOBDRLGH
% open seedqrcode.png 

On iPhone 11 Max Pro using iOS 14.2:

iPhone has no problem focusing, but nothing happens. I do get one "pulse" from haptic, but no import. Done remains disabled. Only choice is to Cancel.

I will note that UR:CRYPTO-SEED/OYADGDFNLDDNPEHFSBTYTTKNIYTLDSSSDYFGLEIOBDRLGH does import into Fehu using text import.

This issue was not an error in Fehu, but an error in how the QR code was generated. The instructions I gave in the seedtool documentation is the source of the error, and I have submitted a PR that fixes the docs.

seedtool outputs a newline character (\n) at the end of its output. This is normal for a command-line tool so the next command prompt or following output appears on the next line. However if this is piped directly into qrencode, then the resulting QR code will also encode the newline. This causes the QR code to not use the more efficient alphanumeric encoding mode, and also causes Fehu to fail to read the code because the newline at the end is not valid ur:crypto-seed syntax. The corrected command to generate the QR code is:

seedtool --ur | tr '[:lower:]' '[:upper:]' | tee /dev/tty | tr -d '\n' | qrencode -o seedqrcode.png -l L

Notice that after the output is piped to the terminal via tee, it is then run through tr again to delete the newline before being piped to qrencode. This fixes the problem.
