Haskell fork that fixes the random tests so that failed tests show the input strings along with some other minor improvements to test generation.

Author changed the link, close the issue

Added in Ruby, done in this fork

std::string o;
...
l = o.length();
char out[l];
...
return out;

• out is a local array variable. with return out; you are returning the address of a local variable, which is incorrect. as soon as the function exits the address becomes invalid.
• out is missing 1 byte for the nul-terminator

Function name typo

Function names misspelled in both.

Fixed, now all tests are guaranteed to have uppercase

the funniest thing is that the only lowercase test; all random tests are using uppercase
