Texts add emphasis information to a string. |
|
343 | 43 |
Texts and strings should behave interchanchably to the outside |
44 |
world, except that texts keep per-character emphasis information. |
|
45 |
(strings return nil, when asked for an elements emphasis). |
|
46 |
Use #string, to get a texts underlying string without any emphasis |
|
47 |
information. |
