This RFE requests full writing system support for Vietnamese.
RFE 4932968 requested support for Vietnamese in the J2RE. In response, support for the vi_VN locale in java.text and java.util functionality was implemented in J2RE 1.5.0 beta 1, and text rendering of precomposed Vietnamese characters was enabled on Windows systems whose fonts support these characters in J2RE 1.5.0 beta 2.
The latter change does not imply full support for the Vietnamese writing system in general. Full support requires some or all of the following additional changes:
- implement rendering of decomposed Vietnamese character sequences in 2D
- provide a font with Vietnamese glyphs for platforms that don't have such fonts
- provide an input method for Vietnamese text input for platforms that don't have Vietnamese keyboard layouts and/or input methods
- additional bug fixes to ensure correct end-to-end handling of Vietnamese text input, layout, and rendering.
