Locale Independence

The library is designed to be locale-independent.

However, there are certain conditions that you should be aware of:

1. You use libc’s setlocale() function to change the locale.
2. Your environment does not adhere to the IEEE 754 floating-point standard (e.g. some IBM mainframes), or you explicitly set YYJSON_DISABLE_FAST_FP_CONV during build, in which case yyjson will use strtod() to parse floating-point numbers.

If both of these conditions are met, it is recommended to avoid calling setlocale() while another thread is parsing JSON. Otherwise, an error may be returned during JSON floating-point number parsing.
