5 Text block: Unicode symbols🔗ℹ

(require text-block/symbols)	package: text-block
(require (submod text-block/symbols unprefixed))
(require (submod text-block/symbols codes))

The text-block/symbols module and its submodules provide bindings and a dictionary to many unicode symbols:

> (require text-block/symbols)
> @zeta
"ζ"

The default prefix is @. To change it, use the unprefixed submodule:

> (require (prefix-in ¶ (submod text-block/symbols unprefixed)))
> ¶zeta
"ζ"

To access the underlying hash table, use the codes submodule:

> (require (submod text-block/symbols codes))
> (hash-ref codes "zeta")
"ζ"

By default, symbols have a different prefix than functions exported by text-block/math to avoid name collisions.
