The ASN.1 TeletexString type supports characters defined in Recommendation T.61 for Teletex applications.
The TeletexString type was originally created for supporting different character sets which could be printed by Teletex machine. It uses special "escape" characters to switch to different character sets. This type should be avoided since UTF8String, BMPString or UniversalString cover all character sets without needing to "escape" into different character sets.
We stand with Ukraine TString ::= TeletexString
A ::= TeletexString a A ::= "AXE"
In BER, the TeletexString type value defined in the example above is encoded as follows:
14 03 415845
The TeletexString type can be constrained by a single value, by size constraints, and by permitted alphabet constraints.
