escapeCaseName

public static String escapeCaseName (String caseName)

Escapes a case name into a valid ResultDB case name. This escaping does NOT support case name with ResultDB's extended depth hierarchy feature, which treats colon as a separator for case name parts.

The escaping is done as follows:

1. If the case name contains non-printable characters, a disallowed leading character ([ !"#$%&'()*+,]), or ends with "\u2051", it undergoes special escaping:
   1. Backslashes (`\`) are escaped to `\\`.
   2. A leading character is escaped with a backslash if it is one of [ !"#$%&'()*+,] (U+0020 to U+002C).
   3. Non-printable characters are converted to their literal unicode escape sequence (\\uXXXX or \\UXXXXXXXX).
   4. A special suffix "\u2051" is appended.
2. On the result of step 1 (or the original string if step 1 was skipped), the following replacements are made:
   1. Backslashes (`\`) are escaped to `\\`.
   2. Colons (`:`) are escaped to `\:`.

This means backslashes can be double-escaped.

DON'T USE this function if you are using ResultDB's extended depth hierarchy feature.

This method is the Java equivalent of the EscapeCaseName function in chrome/engprod/resultdb/go/utils/test_id.go. The round-trip capability with the Go UnescapeCaseName function is tested in the Go codebase.
