There is similar technique called "pseudolocalization", meant for
testing i18n aspect of software.

In one of most common forms, the string

  Edit program settings

woukd be translated to

  [!!! εÐiţ Þr0ģЯãm səTτıИğ§ !!!]

(possibly using mirrored locale, i.e. right-to-left order).

The brackets [!!! ... !!!] are used as a "poison", to detect
translatable text, and to spot issues with truncation; it also helps
with finding "lego" translation.

It would also stress-test Unicode handling...
