Question 1 of 30

Dr. Anya Sharma, a linguist specializing in digital preservation of endangered languages, is working on a project to digitize a collection of ancient texts written in a regional dialect of the Mongolian script. This dialect exhibits several glyphic variations compared to the standard Mongolian script, some of which carry distinct semantic meanings crucial for understanding the texts. Anya needs to ensure that the digital representation accurately reflects these variations and is compatible with modern text processing systems. Considering the principles of ISO 15924 and its relationship with Unicode, what is the most appropriate method for Anya to represent these glyphic variations in her digital archive, ensuring both accurate representation and interoperability across different software platforms? The primary goal is to maintain a clear distinction between glyph variants that carry semantic weight, avoiding ambiguity and preserving the original meaning of the texts for future researchers.

Employ Unicode Variation Sequences (UVS) to differentiate between the glyphic variations, leveraging existing Unicode code points and variation selectors to represent the distinct forms.

Rely solely on font variations to display the different glyphs, assuming that rendering engines will correctly interpret the intended meaning based on the chosen font.

Create entirely new, custom ISO 15924 script codes for each regional variant, ensuring that each glyphic form has a unique identifier.

Utilize Private Use Areas (PUA) within Unicode to encode the variant glyphs, mapping each variation to a specific code point within the PUA range.
