Even in safer languages such as Rust, there are often quæstions as to why certain string operations are either impossible, or need to be quite complicated for a rather simple operation and are then met with responses such as “*Did you know that the length of a string can grow from a capitalization operation depending on locale settings of environment variables?
P.s.: In fact, I would argue that strings are not necessarily all that complicated, but simply that many assume that they are simpler than they are, and that code that handles them is thus written on such assumptions that the length of a string remain the same after capitalization, or that the result not be under influence of environment variables.
