Other orthographies

A variety of issues have made agreement on a standardized orthography for the Igbo language difficult. In 1976, the Igbo Standardization Committee criticized the official orthography in light of the difficulty notating diacritic marks using typewriters and computers; difficulty in accurately representing tone with tone-marking conventions, as they are subject to change in different environments; and the inability to capture various sounds particular to certain Igbo dialects. The Committee produced a modified version of the Ọnwụ orthography, called the New Standard Orthography, which substituted ⟨ ö ⟩ and ⟨ ü ⟩ for ⟨ ọ ⟩ and ⟨ ụ ⟩, ⟨ c ⟩ for ⟨ ch ⟩, and ⟨ ñ ⟩ for ⟨ ṅ ⟩. The New Standard Orthography has not been widely adopted, although it was used, for example, in the 1998 Igbo English Dictionary by Michael Echeruo.

More recent calls for reform have been based in part on the rogue use of alphabetic symbols, tonal notations, and spelling conventions that deviate from the standard orthography.

There are also some modern movements to restore the use of and modernize nsibidi as a writing system, which mostly focus on Igbo as it is the most populous language that used to use nsibidi.
