About this Mod
A mixin patch like InputFix that lets players input multi-byte characters (like Chinese, Korean and Japanese) ingame for Legacy Fabric.
Supports 1.3.2, 1.4.0-1.4.3, 1.4.4-1.4.7, 1.5.X and April Fools 2.0, 1.6.1-1.6.2, 1.6.3-1.6.4, 1.7.10-1.8.9 and 15w14a.
and 1.5.2 Cursed Fabric BTW CE.
Only need Fabric Loader.
The versions for 1.6.4 and below also include a sign input patch. You must install it on Serverside if you want signs with multi-byte characters texts in your -1.6.4 LF server.
Notice
This mod might no longer updated, as most versions were done.
Why there's no 1.7.X : Legacy Fabric's 1.7-1.7.8's mappings are very corrupt, and LF 1.7.9 can't even launch. Send me a github issue if you really want 1.7.2 one.
1.7-1.7.9 Compact:
1.7.X (1.7.0-1.7.9) LF Intermediary mappings can be fixed by https://github.com/HowardZHY/Legacy-Intermediaries/tree/master/mappings. Delete .fabric folder and use a zip software to open .minecraft/libraries/net/fabricmc or legacyfabric/intermediary/[version]/intermediary-1.7..jar, there's a mapping folder in it, download the one from github and rename it to mappings.tiny to replace the one in the mappings folder in the intermediary-1.7..jar then launch the game.
