In Microsoft Word, write fdfa and then press Alt+x to replace fdfa with ﷺ (Darood Shareef).
Who type short cut for darood shareef e.g. saw or pbuh etc. This is valid just in Microsoft Word and doesn't work anywhere else like in webpages or notepad etc. Even more, if you change the fonts, you will get more appropriate samples of darood shareef.
This is neither an ideal nor reliable because in smart phones etc. where Arabic or likewise fonts are not available, this just displays as an empty block similar to other missing Unicode characters whose fonts are not available.
This is a single symbol of complete Arabic text Sallallahu Alaihi Wasallam
.
Note: Alt+x means hold down Alt key on the keyboard and press x and then leave the Alt key.
If you just see an empty block block like Ი or likewise then your browser does not support but works great in Firefox.
