𝕊tring data is far more complex than you might be aware of. The US English alphabet and punctuation are quite simple, but are only a small portion of the available alphabets and non-language symbols. As the need to handle multiple languages, emoji, etc grows, it's important to understand collations and encodings ⦅ https://Collations.Info/ ⦆ before getting collation mismatch errors or losing data.

ℂome learn about: the actual differences between ᴠᴀʀᴄʜᴀʀ and ɴᴠᴀʀᴄʜᴀʀ, what Collations are and can do, Collation Precedence, what server-level and database-level default collations do, Code Pages, Unicode, ASCII / UTF-8 / UTF-16 / UCS-2 / multi-byte character set encodings, character-set conversions and "best fit" mappings, SQL Server vs Windows collations, binary collations (and why they aren't truly case sensitive), supplementary characters and surrogate pairs, combining characters, ramifications of changing a database's collation, sorting, normalization, and other fascinating topics 😺.
