Standard PDF text extractors rely on mapping character codes to glyphs within a font. Because Khmer uses combining marks (vowels and consonants that sit above, below, or to the left/right of the base consonant), a single visual word is often stored out of logical order in the PDF's raw data. Furthermore, Khmer does not use spaces between words, meaning simple extraction will result in a continuous, unreadable block of characters that cannot be easily searched or indexed.

Without proper shaping, the text might appear in the wrong order or as blank boxes. Fortunately, Python’s primary PDF libraries have mature solutions to handle this. Furthermore, Khmer does not use spaces between words,
Unlike English, where characters are simply placed side-by-side, Khmer characters change shape and position based on context. Consonants often stack on top of each other (using subscripts called Cheung Akhar ), while vowels can sit above, below, to the left, or to the right of a base consonant.
