// I was trying to minimize dependencies in this code so that it's easier to port to other terminal applications.
// That's why it doesn't use any of the GSL helpers and makes minimal use of the STL.
#pragma warning(disable : 26446) // Prefer to use gsl::at() instead of unchecked subscript operator (bounds.4).
#pragma warning(disable : 26472) // Don't use a static_cast for arithmetic conversions. Use brace initialization, gsl::narrow_cast or gsl::narrow (type.1).
// On top of that, this code is optimized for processing input as fast as possible, so it's a little low-level.
#pragma warning(disable : 26438) // Avoid 'goto' (es.76).
#pragma warning(disable : 26481) // Don't use pointer arithmetic. Use span instead (bounds.1).
#pragma warning(disable : 26482) // Only index into arrays using constant expressions (bounds.2).
// s_stage1/2/3/4 represents a multi-stage table, aka trie.
// The highest bits of the codepoint are an index into s_stage1, which selects a row in s_stage2.
// The next couple bits of the codepoint then select the column in that row.
// This continues until the last stage which contains the final value.
//
// Fundamentally, the trie is generated by taking all 1114112 codepoints and their assigned values and deduplicating
// chunks of e.g. 16 values each. Each deduplicated chunk is assigned its offset in the list of all deduplicated chunks.
// This results in two lists: 1114112/16=7132 IDs and however many deduplicated chunks you have accumulated.
// This is often called a two-stage table.
//
// If you want to look up the value now, you'll first find the deduplicated chunk offset via `offsets[codepoint / 16]`.
// This gives you the location of your chunk. Now you just look up the value with `values[offset + (codepoint & 15)]`.
//
// Since the 7132 offsets take up a lot more space than the deduplicated values (at least in case of the Unicode database),
// this process can be repeated by compressing the offset array the exact same way the values got compressed and so on.
// s_joinRules represents the UAX #29 extended grapheme cluster rules, however slightly modified to fit our needs.
// Specifically, UAX #29 states:
// > Note: Testing two adjacent characters is insufficient for determining a boundary.
//
// I completely agree, but I really hate it. So this code trades off correctness for simplicity
// by using a simple lookup table anyway. Under most circumstances users won't notice,
// because as far as I can see this only behaves different for degenerate ("invalid") Unicode.
// It reduces our code complexity significantly and is way *way* faster.
//
// This is a great reference for the s_joinRules table:
