One contains a space, one contains a non-breaking space.
Neither are likely to be useful values to send to the server.

non-breaking space is not the same as a space??

a space is "breakable" and and a non-breaking is not.
space = ASCII 20 or 0x20
no-break space = ASCII 160 or 0xA0

Not ASCII, surely? It's

UTF-8: 0xC2 0xA0

Certainly not.
ASCII is 7-bit, from 0 to 127, or 0x00 to 0x7f.

I think the point is, anything >0x7f is not ASCII. 0xA0 is nbsp in
Latin-1 supplement, but a-acute in some other character set (and who
knows maybe something else in another Latin-variant, like that Danish o
with a slash through it etc.).
Scripsit Jonathan N. Little:
>non-breaking space is not the same as a space??
a space is "breakable" and and a non-breaking is not.
They are two distinct characters, though in Unicode, the no-break space
U+00A0 is compatibility equivalent to <noBreakU+002 0 space. Thus, in
principle, the main difference is in line breaking properties. In practice,
other differences can be more important, such as special treatment of U+00A0
as table cell content by web browsers.
Technically, when appearing in an <optionelemen t, the difference of the
codes of the characters is important, since it's the code that is sent as
part of the form data. The rest depends on what the form handler does with
the data.
But what could the difference matter when the character is the sole content
of an <optionelemen t, and why would an author use such a degenerated
element? I'm afraid the OP is getting farther from his original problem and
potentially generating new problems. Explaining the _real_ problem might be
a good start.

I have a bunch of select statements in a form, and each select statement

It seems you cannot 'onchange' a single option!
Well, that is reasonable.

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
