We also find that text like this is incredibly commonโ-โparticularly on social media.
Another pain-point comes from diacritics (the little glyphs in ร, รฉ, ร ) that you'll find in almost every European language.
These characters have a hidden property that can trip up any NLP modelโ-โtake a look at the Unicode for two versions of ร:
Latin capital letter C with cedilla: \u00C7
Latin capital letter C + combining cedilla: \u0043\u0327
Both are completely different, despite rendering as the same character.
To deal with all of these text variants we need to use Unicode normalization - which we will cover in this video.
