After following the steps from use-cases.html#experiment-with-hellodebot,
the last step

 ft client -- debot fetch %{account:address:my-first-debot}

fails with following error :

It looks like an error caused by changes in the new versions of solc, tvm_linker and tonos-cli. Character '7' is because the ABI file stored using setABI is in hexa, and starts with '7'. However, bytes are automatically converted from hexa, so the problem comes from having the new type string instead of bytes in the ABI, that requires a non-hexa encoding.

I added a new substitution escape:SUBST that can be used to automatically json-escape a string, it could be used instead of the hex:SUBST substitution in the example. However, the new version of ft will only build with the new version of freeton_ocaml_sdk 0.5.0 that needs to be released...
