In linguistics, the following Greek letters must take on a special ‘Latin’ shape, and in the Brill typeface these glyph shapes are accessible either via a dedicate dedicated Unicode point (which is preferred), or via the OpenType Stylistic Set 20:
| Greek | Unicode | Latin shape (Stylistic Set 20) | Latin shape (Unicode) | Unicode Latin shape |
|---|---|---|---|---|
 | U+03B2 | (do not use) |
| U+A7B5 |
 | U+03B8 |
| ||
 | U+03BB |  | ||
| U+03C7 | (do not use) |
| U+AB53 |
NoteImportant note: Even when the author has correctly applied the correct OpenType stylistic set to characters listed above, editors must still mark them for the typesetters, and the latter must be instructed to replace such characters with dedicated characters whenever available, such as in the case of ꞵ and ꭓ (U+A7B5, U+AB53). The OpenType ss20 attribute does not, unfortunately, carry over to most page layout applications such as Adobe InDesign!
