Hello [name]! Thanks for joining the GMC. Before making any posts in the Tech Support forum, can we suggest you read the forum rules? These are simple guidelines that we ask you to follow so that you can get the best help possible for your issue.
Adding Hebrew's range (1424-1535) is pointless if the font you chose doesn't come with the glyphs. Check the font in Character Map, don't just rely on the preview. The preview steals glyphs from other fonts if the selected font doesn't have it, giving the wrong impression that it works even when it doesn't.
Also, you should know that GM's sprite-based font rendering system doesn't have built-in support for right-to-left or CTL text. There are ways for adapting the system, but nothing official.
