For example, python's sqlite3 will * convert unicode strings to UTF-8 (py2 and py3) {{verify}} * it seems ** py2 sent str (its bytestrings) as-is (and since the library didn't check, you better hope it was valid UTF-8) {{verify}} ** and py3's bytes going to text fields isn...")

Pointing out that something is bimodal often comes up in cases where it's convenient to simplify into something with two distinct, clearly separated cases, and more so in cases where that is a simplification with problems.")

It is contrasted with kernel space We tend to use this term when it may also be reasonable to do the thing in the kernel 'space' refers more to to memory space, e.g. where things are ''stored'', but it is often implied things are also ''computed'' in the same place (as the kernel, versus as a user).
