The support for complex text rendering for personal computers did not arrive until Windows XP Service Pack 2 in 2004, and a Burmese font utilizing this technology did not exist until 2005.

[6] With the advent of mobile phones, manufacturers such as Samsung and Huawei simply replaced the Unicode compliant Burmese system fonts with their Zawgyi equivalents.

As a separate encoding, the situation leads to garbled text being shown between users of Zawgyi and Unicode.

[9][needs update] Unicode uses the private-use script code Qaag to mark text written in Zawgyi.
