uint8_t formatted as a character by default

[Nekotekina]

Hi!

Was it indended that the value of std::uint8_t type becomes a character if formatted as {}? It was slightly confusing.

Hi, @Nekotekina.

No, this is not intentional, but an unfortunate consequence of std::uint8_t being defined as unsigned char. It might be worth changing the default format of unsigned char and signed char to numeric, but other potentially undesirable side-effects must be considered.

In the meantime you can format std::uint8_t using a numeric format specifier such as d:

  std::uint8_t u = 42;
  fmt::format("{:d}", u);

or promoting the argument to int:

  fmt::format("{}", +u);
