Some kanji have alternative writings that are significantly different from each other (e.g. different numbers of strokes). For example, see here.
I'm looking for ways to find alternative writings for a given kanji in electronic form (that I can copy-paste as text; IOW, bitmapped images won't do).
Does anyone know of an online reference for finding alternative drawings of a character?
NB: I wrote the example below before I was aware of the issues that Shen Kuo explained in his first answer. I now realize that this example is likely to be confusing rather than illuminating to most readers. I've kept it as is, since several comments and at least one answer refer to it. If you do find it confusing, please ignore it.
For an example of the sort of search I'm trying to perform, consider the character
Every place I've looked online shows the second character of the compound そうち (device) like this:
Note that the last stroke of this character is a simple horizontal one across the bottom.
In contrast, I have a several printed sources that show a different writing for the second character of this compound, where the last stroke consists of a vertical component along the left side of the character, followed by a horizontal one across the bottom; some instances are shown below:
Note the last two characters in both books' titles. These two characters are supposed to be the compound 装置, but the second one of the characters is drawn differently from 置1. Incidentally, my old Nelson kanji dictionary (2nd revised edition, 1974; 17th printing, 1984) shows the same drawing of this character as that shown in the picture above (see character 3644). AFAICT, it does not mention the form 置 at all.
FWIW, none of the search tools that I've tried that accept handdrawn characters as input have retrieved the alternative form of 置.
1These books use this alternative drawing of 置 throughout, not just in their cover titles. If you right-click on the image, and open it at full resolution in a different tab, you will be able to find other instances of this alternative drawing of 置 besides those appearing in the main titles.
