U1780U17FF

The range U+1780 to U+17FF forms the Khmer block in the Unicode standard, designated for encoding the Khmer script used by the Cambodian language. This block enables the representation of Khmer text in digital systems and supports the orthography used in modern and historical materials.

The Khmer block contains a set of consonant letters, independent vowels, and a variety of diacritic marks that modify consonants to indicate different sounds and syllable structures. It also includes combining marks used to form the complex vowel system of Khmer, where vowels can attach to or modify consonants. In addition to letters and diacritics, the range provides Khmer numerals for digits and basic punctuation marks essential for written text. The design accommodates the script’s typical abugida-like behavior, where vowel signs interact with consonants to produce syllables.

In practical use, text within this range is rendered by fonts and shaping engines that support Khmer typography. Proper rendering often requires a font with Khmer glyphs and a text layout engine capable of handling combining marks and complex script shaping. The Khmer block is widely used for Cambodian-language content on websites, documents, educational resources, and digital communications, contributing to the broader support of global scripts in Unicode.

References to the block are commonly framed in terms of its Unicode range (U+1780–U+17FF) and its role in encoding the Khmer writing system within the Unicode ecosystem.
