Instance Method Details

#call ⇒ Array<Array<Integer>>

Return start and end indexes for all so-called “non-Latin” sub-strings of the input string. Numbers and some punctuation characters can be part of both Latin, and non-Latin sub-strings. The “locale” of these characters is defined by the preceding character(s). E.g., in the string “привет-123 hello-456” the “-123 ” chunk (note the trailing space) would be considered as a part of the non-Latin sub-string, while the “-456” chunk as a part of the Latin sub-string.

Sometimes it is required to forcibly apply the Latin ‘locale’ to the character. This is needed to avoid some bugs in the legacy software (e.g. MK90 BASIC). For this purpose there’s the optional argument ‘forced_latin’.
