Base62 encoding converts numbers to ASCII strings (0-9, a-z and A-Z) and vice versa, which typically results in comparatively short strings. Such identifiers also tend to more readily identifiable by humans.
译文：Base62编码将数字转换为ASCII字符串（0-9、a-z和a-z），反之亦然，这通常会导致相对较短的字符串。这种标识符也往往更容易被人类识别。
例如：
999 => "g7"
9999 => "2Bh"
238327 => "ZZZ"
