SPDX tag for this Unicode source license

[Peter Lemenkov]

Hello! I've stumbled upon the following legal text (a bunch of usually
bundled UTF-conversion routines are licensed under this one):

```
Copyright 2001-2004 Unicode, Inc.

made as to fitness for any particular purpose. No warranties of any
kind are expressed or implied. The recipient agrees to determine
applicability of information provided. If this file has been

sole remedy for any claim will be exchange of defective media
within 90 days of receipt.

Unicode, Inc. hereby grants the right to freely use the information
supplied in this file in the creation of products supporting the
Unicode Standard, and to make copies of this file in any form
for internal or external distribution as long as this notice
remains attached.
```

What's the proper SPDX tag for this one? License checking tool during
the fedora-review says its "Unicode strict" but license-fedora2spdx
doesn't know about this one although it is a quite popular one
according to GitHub

This license is `LicenseRef-Unicode-legacy-source-code` and is *not-allowed*
https://gitlab.com/fedora/legal/fedora-license-data/-/blob/main/data/License...

However, in at least some cases we've concluded that the license is
irrelevant because it is associated with stuff that is presumed not to
require a license. There have been other situations where a later,
less problematic Unicode license was introduced to cover stuff
purportedly covered by an earlier non-FOSS Unicode license. Please
open an issue at fedora-license-data and we can review the specific
case you're encountering.

Ah snap.

I'm afraid in my case it cannot be ignored. I am trying to add
unshield application to Fedora which is used for extracting
InstallShield archives. The code licensed under
LicenseRef-Unicode-legacy-source-code is used for converting filenames
from UTF16 to UTF8. Good news I just reimplemented it under MIT
license, submitted upstream where my code was accepted already!
