- L1. On each line, reset the embedding level of the following characters to the paragraph embedding level: 1. Segment separators, 2. Paragraph separators, 3. Any sequence of whitespace characters and/or isolate formatting characters (FSI, LRI, RLI, and PDI) preceding a segment separator or paragraph separator, and 4. Any sequence of whitespace characters and/or isolate formatting characters (FSI, LRI, RLI, and PDI) at the end of the line.

array<string|int, mixed> —processL1()
L1. On each line, reset the embedding level of the following characters to the paragraph embedding level: 1. Segment separators, 2. Paragraph separators, 3. Any sequence of whitespace characters and/or isolate formatting characters (FSI, LRI, RLI, and PDI) preceding a segment separator or paragraph separator, and 4.

protected processL1()
: mixed
Return values
mixed —processL1b()
Internal L1 step
protected processL1b(int $idx,
int $jdx)
: mixed
Parameters
- $idx : int

-
Current index
Return values
mixed —processL2()
L2. From the highest level found in the text to the lowest odd level on each line, including intermediate levels not actually present in the text, reverse any contiguous sequence of characters that are at that level or higher.
protected processL2()
: mixed
This rule reverses a progressively larger series of substrings.
