(For OSC and ST, their C0 variant was shown above. They have another, C1 form which might be supported in some contexts. In 8-bit Latin-X character sets they are the single bytes 0x9d and 0x9c, respectively. In UTF-8 mode some terminal emulators deliberately do not implement C1 support because these bytes would conflict with the UTF-8 encoding, while some other terminal emulators recognize the UTF-8 representation of U+009d (i.e. 0xc2 0x9d) and U+009c (i.e. 0xc2 0x9c), respectively. Since C1 is not universally supported in today's default UTF-8 encoding, its use is discouraged.)
