In the WebContainer terminal, node -e mishandles \r and \n and other special characters when written using process.stdout.write(). Plain stdout output works. ANSI/control bytes also work.
These commands work:
node -e 'process.stdout.write("hello")'node -e 'process.stdout.write("hello$")'node -e 'process.stdout.write("hello" + String.fromCharCode(13) + "$")'node -e 'process.stdout.write(Buffer.from([104,101,108,108,111,13,36]))'
node -e 'const cr="\x0d"; process.stdout.write("hello"+cr+"$")'This command fails:
node -e 'process.stdout.write("hello\r$")'❯ node -e "console.log('\n')"
