Using Unicode directional formatting characters in file names

Question

The Unicode standard is constantly being updated. The latest version 13.0 was released in March 2020. Please note that often in new versions of Unicode standard not only new characters are added, but also changes occur in various algorithms that are an integral part of the standard itself.

I want to get answers to the following questions:

1. What version of Unicode standard is used in Windows 10 21H1?
2. Does Windows 10 21H1 support Explicit Directional Isolate Formatting Characters: LRI, RLI, FSI, PDI, which appeared in version 6.3 of the Unicode standard?

Unicode Bidirectional Algorithm recommends to use the Explicit Directional Isolate Formatting Characters (LRI, RLI, FSI, PDI) instead of Explicit Directional Embedding and Override Formatting Characters (LRE, RLE, LRO, RLO, PDF):

Sometimes I use bidirectional file names: a mixture of right-to-left (Hebrew) and left-to-right text (English).

I have no problems with using of non-recommended Explicit Directional Embedding and Override Formatting Characters (LRE, RLE, LRO, RLO, PDF), but recommended Explicit Directional Isolate Formatting Characters (LRI, RLI, FSI, PDI) don't affect the ordering of characters.
