Attach your transferguard_i18n_zh-TW.properties here (press “Use advanced editor” in the top right and then “Attach”), i will try adding it to Spark myself.
Currently voice chat support in Spark is broken and there is no clue when it will be working (nobody is currently working on fixing it).
This wasn’t working for your probably because you haven’t built the plugins themselves. Building only Spark doesn’t build changes in plugins, so you have to run build-plugins Ant task first. I have added your translation for Transfer Guard into Spark’s source (https://igniterealtime.org/issues/browse/SPARK-1653). You can find this translation in the latest nightly build (729): Ignite Realtime: Spark Nightly Builds
The ideal way would be to make a PR with your changes on GitHub, so i would only have to approve it. But that’s could be too much for you. Another way would be to provide a diff patch with your changes, so it could be applied to the source. Again, you would have to know how to generate a diff. So, a third way it just attach updated translation files here and i will copy them over the old ones and apply to the source.
Next time just add all files into one zip and attach it. I have just applied these new translations to the source. Some places are still showing in English. You can test it in 731 build Ignite Realtime: Spark Nightly Builds
Never mind. I saw those English entries after compiling Spark in Eclipse, but i haven’t compiled plugins at that point. Now when i have installed new version with an installer i see everything is translated indeed.
