/**
* Pseudolocalizations
*
* PSEUDO_STRATEGIES is a dict of strategies to be used to modify a
* context in order to create pseudolocalizations. These can be used by
* developers to test the localizability of their code without having to
* actually speak a foreign language.
*
* Currently, the following pseudolocales are supported:
*
* accented - Ȧȧƈƈḗḗƞŧḗḗḓ Ḗḗƞɠŀīīşħ
*
* In Accented English all Latin letters are replaced by accented
* Unicode counterparts which don't impair the readability of the content.
* This allows developers to quickly test if any given string is being
* correctly displayed in its 'translated' form. Additionally, simple
* heuristics are used to make certain words longer to better simulate the
* experience of international users.
*
* bidi - ɥsıʅƃuƎ ıpıԐ
*
* Bidi English is a fake RTL locale. All words are surrounded by
* Unicode formatting marks forcing the RTL directionality of characters.
* In addition, to make the reversed text easier to read, individual
* letters are flipped.
*
* Note: The name above is hardcoded to be RTL in case code editors have
* trouble with the RLO and PDF Unicode marks. In reality, it should be
* surrounded by those marks as well.
*
* See https://bugzil.la/1450781 for more information.
*
* In this implementation we use code points instead of inline unicode characters
* because the encoding of JSM files mangles them otherwise.
