Function Reference

Page 833 of 839

The function supports also specific Unicode characters which are used to control the bidirectional

algorithm. The bidirectional formatting codes are also supported by all other text functions.

Character code (Hex)

Description

0x202A

LRE Left-to-Right Embedding (treat the following text as embedded left-to-right)

0x202B

RLE Right-to-Left Embedding (treat the following text as embedded right-to-left)

0x202C

PDF Pop Directional Format (restore the bidirectional state to what it was before

the last LRE, RLE, LRO or RLO)

0x202D

LRO Left-to-Right Override (force the following characters to be treated as

strong left-to-right characters)

0x202E

RLO Right-to-Left Override (force the following characters to be treated as

strong right-to-left characters)

0x200E

LRM Left-to-Right Mark (left-to-right zero-width character)

0x200F

RLM Right-to-Left Mark (right-to-left zero-width character)

0x200C

Zero width non-joiner

0x200D

Zero width joiner

The bidirectional code pages 1255 and 1256 support the character codes 0x200E and 0x200F only (the

mapped codes are 253 and 254).

Note that the Unicode character codes are supported by the Unicode version of the function only.

Escape Sequences

In situations where an alignement or command tag should be output as plain text it is possible to

precede the tag with an additional backslash. This marks the string as plain text and the function

does not interpret it as command or alignment tag. The first backslash is treated as escape character

and will be removed.

Example:

\\

= \\

\\ce#

= \ce#

\\\le#

= \\le#

\\LI [...] = \\LI [...] // No valid tag -> always processed as text

\\LI[...]

= \LI[...]

The function compares the first four characters of command tags which accept parameters . If the

sequence matches a command tag an additional backslash is required if the string should be output

as text.

It is also possible to fully disable alignment and command tags with the flag taPlainText that can be

passed to the parameter Align. Combine the flag with the wished alignment constant with a binary

or operator, e.g. (TTextAlign)(taRight | taPlainText). This can be useful when it is known that the
