Main template {{PD-Unicode}} can be used for licensing as well as for categorizing.

Its sub-templates like {{PDUdiff2}} help to diffuse the crowded main category PD Unicode. Some diffusion is done in {{PD-Unicode}}, as to select the plane (BMP, SMP, SIP).
The BMP comprises many Unicode blocks as is shown in the table in Unicode BMP. Therefore the BMP is diffused into BMP-0, BMP-1, BMP-2 and so on.
For further diffusion within the most crowded BM-plane, the selection can be solved by different sub-templates like {{PDUdiff0}}, {{PDUdiff1}}, {{PDUdiff2}}, {{PDUdiff3}} (and so on, as required).

Note:This splitting simplifies a lot the selection and maintenance, and saves from repeated creation of in-between parameters.

Usage[edit]

{{PDUdiff2}} gets from PD-Unicode one single parameter, a hexadecimal numer between 200 and 2FF, the first three digits of the code point value. It returns a code of a hexadecimal number "xx" between 00 and FF, where 2xx0 is the first code point address of the Unicode block to which the character belongs.

Note: It would be not only sufficient but much better to pass to PDUdiff2 two hexdigits xx instead of three 2xx, leaving away the redundant heading 2; leaner coding would be possible. But while Wikimedia template parsing allows to strip easily trailing parts of a parameter string, the stripping of leading parts is not supported and would cause unacceptable server work.

As an example, the Braille glyph at U+283D Braille Y.svg and any other glyph between U+2800 and U+28FF is categorized into PD Unicode-BMP-2800, because the Braille letters are in Category:Unicode 2800-28FF Braille Patterns.
On the other hand, U+253B.svg is categorized into PD Unicode-BMP-2500 because it belongs to Unicode 2500-257F Box Drawing.
