Recently there have been attempts to standardize and simplify the script, e.g. by using x for [z] and a single s for [s]; then one would write baxa for ("she kisses") and basa for ("low"). Another recent convention is to use l for the "soft" l, to allow a more unified orthography for all variants of the language. However, in spite of their theoretical advantages, these proposals have not been very successful outside of academic circles, because of regional variations in pronunciation and incompatibility with existing literature.
The Venetian speakers of Chipilo use a system based on Spanish orthography, even though it does not contain letters for [j] and [?]. The American linguist Carolyn McKay proposed a writing system for that variant, based entirely on the Italian alphabet. However, the system was not very popular.
