Kuomintang rule in Taiwan, the official Kuomintang language policy was to promote the use of Mandarin Chinese in everyday speech, and to discourage the use of other dialects such as Hokkien and Hakka; this was done in an attempt to promote national linguistic unity, and to promulgate a Chinese identity over that of a Taiwanese one for political reasons. Following the Taiwan localization movement, education and everyday usage of spoken and written Hokkien by local Taiwanese became more widely used. A Chinese character online dictionary for Hokkien was released in 2008 by the ROC Ministry of Education. Nevertheless, within literature circles there is still ongoing debate over which writing system should be used to write Taiwanese Hokkien, and controversy exists between the various rival systems currently used to write Hokkien. Today usage of languages remains a politicized issue in Taiwan. In Singapore, in an effort to promote Mandarin as a lingua franca amongst ethnic Chinese through the Speak Mandarin Campaign, usage of other varieties such as Hokkien is discouraged. Today, whilst Taiwanese Hokkien speakers speak in their variety of Hokkien, they would officially write in Vernacular Chinese for formal documents, and only use vernacular Hokkien writings during informal occasions, if at all. In Taiwan, vernacular Chinese is used for academic writings, newspaper articles and television news report headlines, whilst Hokkien writings are used in novels, songs lyrics, film subtitles, theatrical and opera scripts, and in informal communication. Phonetic writing systems Pe̍h-ōe-jī Pe̍h-ōe-jī () is a Latin alphabet developed by Western missionaries working in Southeast Asia in the 19th century to write Hokkien. Pe̍h-ōe-jī allows Hokkien to be written phonetically in the Latin script, meaning that phrases specific to Hokkien can be written without having to deal with the issue of non-existent Chinese characters. Currently usage of Pe̍h-ōe-jī is restricted to some Taiwanese Christians, non-native learners of Hokkien, and native-speaker enthusiasts in Taiwan. POJ remains the Taiwanese script with "the richest inventory of written work, including dictionaries, textbooks, literature [...] and other publications in many areas". Pe̍h-ōe-jī can also be used along with Chinese characters in a mixed script called Hàn-lô, where words specific to Hokkien are written in Pe̍h-ōe-jī, and words with associated characters written in Han Characters.
