- Paranoid strcpy into a buffer of given length (includes terminating
- zero. Strips out all but 'a-Z0-9' and the character in other_safe_chars
- and replaces with '_'. Deliberately does *NOT* check for multibyte
- characters. Treats src as an array of bytes, not as a multibyte
- string. Any byte >0x7f is automatically converted to '_'.
- other_safe_chars must also contain an ascii string (bytes<0x7f).
