The bug
The Hebrew language is written from right to left.
Starting with version 1.15 the language display is left to right and it is unreadable.
So far the switch between languages would correct the text to readable (see MC-174932), but in version 20w17a this workaround no longer works. Even after switching the language in the menu, the text is still unreadable.
How to reproduce
Go to Options -> Language and select Hebrew (Looks like this: (ישראל) עברית)

Investigating this further, this seems to be a new bug in the snapshots.
In 1.15.2 this did not happen after changing the language in the menu, (but it did happen after restarting Minecraft with an RTL language selected as default, see MC-174932)
However, even after right after switching the language, unlike 1.15.2, the text is still in the wrong order in 20w17a. Restarting also does not fix this issue.
This should be marked as resolved.
Why?
It is not fixed and still an issue.
I reckon it got broken due to the recent unicode/font changes.
