| 1636 | - * | |
| 1637 | - * pseudo is a dict of strategies to be used to modify the English | |
| 1638 | - * context in order to create pseudolocalizations. These can be used by | |
| 1639 | - * developers to test the localizability of their code without having to | |
| 1640 | - * actually speak a foreign language. | |
| 1641 | - * | |
| 1642 | - * Currently, the following pseudolocales are supported: | |
| 1643 | - * | |
| 1644 | - * fr-x-psaccent - Ȧȧƈƈḗḗƞŧḗḗḓ Ḗḗƞɠŀīīşħ | |
| 1645 | - * | |
| 1646 | - * In Accented English all English letters are replaced by accented | |
| 1647 | - * Unicode counterparts which don't impair the readability of the content. | |
| 1648 | - * This allows developers to quickly test if any given string is being | |
| 1649 | - * correctly displayed in its 'translated' form. Additionally, simple | |
| 1650 | - * heuristics are used to make certain words longer to better simulate the | |
| 1651 | - * experience of international users. | |
| 1652 | - * | |
| 1653 | - * ar-x-psbidi - ɥsıʅƃuƎ ıpıԐ | |
| 1654 | - * | |
| 1655 | - * Bidi English is a fake RTL locale. All words are surrounded by | |
| 1656 | - * Unicode formatting marks forcing the RTL directionality of characters. | |
| 1657 | - * In addition, to make the reversed text easier to read, individual | |
| 1658 | - * letters are flipped. | |
| 1659 | - * | |
| 1660 | - * Note: The name above is hardcoded to be RTL in case code editors have | |
| 1661 | - * trouble with the RLO and PDF Unicode marks. In reality, it should be | |
| 1662 | - * surrounded by those marks as well. | |
| 1663 | - * | |
| 1664 | - * See https://bugzil.la/900182 for more information. | |

| 72 | -/* Pseudolocalizations | |
| 73 | - * | |
| 74 | - * pseudo is a dict of strategies to be used to modify the English | |
| 75 | - * context in order to create pseudolocalizations. These can be used by | |
| 76 | - * developers to test the localizability of their code without having to | |
| 77 | - * actually speak a foreign language. | |
| 78 | - * | |
| 79 | - * Currently, the following pseudolocales are supported: | |
| 80 | - * | |
| 81 | - * fr-x-psaccent - Ȧȧƈƈḗḗƞŧḗḗḓ Ḗḗƞɠŀīīşħ | |
| 82 | - * | |
| 83 | - * In Accented English all English letters are replaced by accented | |
| 84 | - * Unicode counterparts which don't impair the readability of the content. | |
| 85 | - * This allows developers to quickly test if any given string is being | |
| 86 | - * correctly displayed in its 'translated' form. Additionally, simple | |
| 87 | - * heuristics are used to make certain words longer to better simulate the | |
| 88 | - * experience of international users. | |
| 89 | - * | |
| 90 | - * ar-x-psbidi - ɥsıʅƃuƎ ıpıԐ | |
| 91 | - * | |
| 92 | - * Bidi English is a fake RTL locale. All words are surrounded by | |
| 93 | - * Unicode formatting marks forcing the RTL directionality of characters. | |
| 94 | - * In addition, to make the reversed text easier to read, individual | |
| 95 | - * letters are flipped. | |
| 96 | - * | |
| 97 | - * Note: The name above is hardcoded to be RTL in case code editors have | |
| 98 | - * trouble with the RLO and PDF Unicode marks. In reality, it should be | |
| 99 | - * surrounded by those marks as well. | |
| 100 | - * | |
| 101 | - * See https://bugzil.la/900182 for more information. | |

| 1680 | - * | |
| 1681 | - * pseudo is a dict of strategies to be used to modify the English | |
| 1682 | - * context in order to create pseudolocalizations. These can be used by | |
| 1683 | - * developers to test the localizability of their code without having to | |
| 1684 | - * actually speak a foreign language. | |
| 1685 | - * | |
| 1686 | - * Currently, the following pseudolocales are supported: | |
| 1687 | - * | |
| 1688 | - * fr-x-psaccent - Ȧȧƈƈḗḗƞŧḗḗḓ Ḗḗƞɠŀīīşħ | |
| 1689 | - * | |
| 1690 | - * In Accented English all English letters are replaced by accented | |
| 1691 | - * Unicode counterparts which don't impair the readability of the content. | |
| 1692 | - * This allows developers to quickly test if any given string is being | |
| 1693 | - * correctly displayed in its 'translated' form. Additionally, simple | |
| 1694 | - * heuristics are used to make certain words longer to better simulate the | |
| 1695 | - * experience of international users. | |
| 1696 | - * | |
| 1697 | - * ar-x-psbidi - ɥsıʅƃuƎ ıpıԐ | |
| 1698 | - * | |
| 1699 | - * Bidi English is a fake RTL locale. All words are surrounded by | |
| 1700 | - * Unicode formatting marks forcing the RTL directionality of characters. | |
| 1701 | - * In addition, to make the reversed text easier to read, individual | |
| 1702 | - * letters are flipped. | |
| 1703 | - * | |
| 1704 | - * Note: The name above is hardcoded to be RTL in case code editors have | |
| 1705 | - * trouble with the RLO and PDF Unicode marks. In reality, it should be | |
| 1706 | - * surrounded by those marks as well. | |
| 1707 | - * | |
