Embed right-to-left text correctly in your documents.
BDI (Bidirectional Isolate) is used to isolate text with different directionality, preventing it from affecting surrounding text direction.
RLE (Right-to-Left Embedding) is used to set the bidirectional level of text to right-to-left, useful for embedding RTL text within LTR contexts.
PDF (Pop Directional Formatting) ends the effect of RLE, LRE, or other embedding marks, restoring the previous bidirectional state.
