This API only supports a limited set of codepoints for conversion and is not suitable as general purpose Unicode-aware case conversion function.
The table below documents support for uppercase characters within defined Unicode codepoint blocks. A block is considered "supported" only if all uppercase class characters within the block will be converted to their lowercase equivalents by this function.
| Block Name | Supported | Notes |
|---|---|---|
| Basic Latin | ✔️ | |
| Latin-1 Supplement | ✔️ | |
| Latin Extended-A | ❌ | Limited support for Œ (U+0152) and Ÿ (U+0178) only.

Example[]
This example demonstrates the support for the Basic and Supplemental Latin codepoint ranges, outputting a lowercased pair of strings.
local basic = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"
local supplemental = "ÀÁÂÃÄÅÆÇÈÉÊËÌÍÎÏÐÑÒÓÔÕÖØÙÚÛÜÝÞ"
print(CaseAccentInsensitiveParse(basic))
print(CaseAccentInsensitiveParse(supplemental))
-- Prints:
-- abcdefghijklmnopqrstuvwxyz
-- àáâãäåæçèéêëìíîïðñòóôõöøùúûüýþ
