Regarding or relating to orthography (the way in which languages, usually natural languages, are written).

Although it is possible to represent this phonetic distinction orthographically, such representation is not emically realized.

In some cases clusters appear orthographically but could correspond to a specific speech sound (phoneme) and therefore it cannot be considered a cluster, for instance dzhush /d͡ʒuʃ/ ‘juice’.

According to standardized or formally accepted orthography: using proper spelling, and (more strictly) proper spelling, punctuation, capitalization, and italics.

stylings that are orthographically valid (acceptable), albeit not preferable

For example, in Mathematics, the SVL includes find and set, which are not as orthographically complex as other entries such as quadrilateral or trigonometric, and furthermore commonly occur outside mathematics.

Using an orthographic projection (a way of showing three-dimensional objects in two-dimensional engineering drawings).

To represent an internal feature orthographically, dashed lines are used instead of solid ones.
