Purpose
This is a Rust library for doing character replacement on strings. A standard character substitution definition file have a string of characters for the input substitution, followed by white space and then the replacement text. For example, the standard TeX input conventions can be reproduced using:
` ‘
`` “
' ’
'' ”
-- –
--- —
!` ¡
?` ¿
~ \u{a0}
Escaping is handled following Rust conventions. If white space is to be used in the
source or replacement text, it should be entered using escape codes (so \u{20}
) to
get a space. I wouldn't recommend that, however.
Another example showing Sylvio Levy's scheme for input of classical Greek with ASCII input:¹
a α
'a ά
`a ὰ
~a ᾶ
>a ἀ
>'a ἄ
>`a ἂ
>~a ἆ
<a ἁ
<'a ἅ
<`a ἃ
<~a ἃ
α| \u{1fb3}
'a| \u{1fb4}
`a| \u{1fb2}
~a| \u{1fb7}
>a| \u{1f80}
>'a| \u{1f84}
>`a| \u{1f82}
>~a| \u{1f86}
<a| \u{1f81}
<'a| \u{1f85}
<`a| \u{1f83}
<~a| \u{1f87}

This is not meant as a replacement for a shaping library, but as a supplement to it. In finl, charsubs will be applied before the shaping library is called but after all formatting commands
