I need to create a variable labeled fc' to represent the compressive strength of concrete("f" and apostrophe being on the normal typing line, and "c" being treated as a subscript). From looking online I have come across round about ways of inputting similar variables using the Windows Character Map. Some characters are available in the character map that SMath will treat as a normal line of typing character, but the character displays as a subscript, such as U+2093: Latin Subscript Small letter X. Unfortunately, nothing is available for c.

Any help is appreciated.

Thanks

f apostrophe dot c

As for now, the simplest way is to use f'.c (that is widely used too).

I know ACI 318 has f.c^’, but there is not yet a way to freely mix baseline/subscript/superscript characters (also, superscript characters are only the ones available from the unicode tables).

Hi. As Davide says, there are only some few characters for subscripting with Unicode chars. This is a workaround for this case and some others:



fc'.sm (4 KiB) downloaded 28 time(s).

... as you type f, you have 3 useful upper-script:
coma, Alt238, Alt248
and about 75 sub-script form AltKey

An arabic damma sign combined with latin f.
And two spaces to ensure it doesn't overlap.
Copy paste text below to smath.
Maybe this helps.

fُ.c\0020\\0020\
