// Functions for "inline string encoding" handling,
|
|
// a simple encoding-form used for encoding strings that can't contain control codes and a few other special characters,
|
|
// so they can be stored as part of a field in an ASS line
|
|
|
|
// Even though the encoding will handle unicode strings, it can only encode ASCII characters.
|
|
// This is not a problem, since only ASCII characters are used for the special purposes.
|
|
|
|
// The encoding is based on an escape-character followed by a two-digit hexadecimal number, the number being the
|
|
// ASCII code for the encoded character. The escape character is # (ASCII 0x23).
|
|
|
|
// The following ASCII codes must be escaped:
|
|
// 0x00 .. 0x1F -- Control codes (nonprintable characters, including linebreaks)
|
|
// 0x23 -- Sharp (the escape character itself must be escaped to appear in the literal)
|
|
// 0x2C -- Comma (used for field separator in standard ASS lines)
|
|
// 0x3A -- Colon (used in some custom list formats for name:value pairs)
|
|
// 0x7C -- Pipe (used in some custom lists, as item separator, eg. itemA|itemB)
|
|
|
|
// The encoded string should be usable in any kind of field in an ASS file.
