i need a font in which i can get the alphabet "c" with a bar over it, which means "with" in medical term. i.e. C letter with a bar on it.

Do you mean a C Macron ? (Sorry, link in French, no page in English on Wikipedia)

yaa, exactly the same. thanks but how can i use it ... i hv to type it in Photoshop so i hv to get the font.

Then I'm not sure it's a c macron, especially since you're talking about a medical term. Maybe you have an example of this c in use ? The best would be a link to a website, or a .pdf file, anything.

Well thanks a lot for ur concern. Take care. God Bless you

How do you intend to use this? Only as an image (Photoshop) and or only for printing yourself or as a text document for word processing or a pdf that can also be used by others?

Edit kk
Please use capitals and proper punctuation. Makes your writing less a puzzle.

actually, i have a hobby of making funny pictures and putting funny quotes and i make it in photoshop, i do use text in it in the end saying my name .i.e. With Love (heart shape) K@p!lL (kapil i.e. my name).so i dont want to write "with" the whole word i want to write "c with a dash" so it will be more creative ... that way ...

Didn't I mumble something about using capitals and proper punctuation?
