Sensitive to the current key script or font script (as appropriate),
HyperCard invokes special-case code for handling non-Roman text
characteristics as necessary.
Additionally, HyperCard 2.2 properly displays fields that contain
double-byte characters, bidirectional text, or contextual ligatures, as
long as the relevant script is installed on the computer. (The script no
longer needs to be the system script.)
This means that HyperCard can now show languages such as Japanese, Arabic,
Korean, and Traditional Chinese without the problems of previous versions.
