Texts add emphasis information to a string. |
|
4015 | 51 |
|
343 | 52 |
Texts and strings should behave interchanchably to the outside |
53 |
world, except that texts keep per-character emphasis information. |
|
4015 | 54 |
(strings return nil when asked for an element's emphasis). |
3689 | 55 |
Use #string, to get a text's underlying plain string without any emphasis |
343 | 56 |
information. |
