California has to adopt a new license plate plan soon - see https://manifold.markets/StrayClimb/after-california-runs-out-of-plates

When this plan is announced market is YES if it will allow for nonalphanumeric characters, from other languages, such as chinese characters, hindi letters, native alphabets, etc. Note that english punctuation doesn't count, but non-English language punctuation would.

Spanish Ñ or ñ would count as YES, as would foreign accented letters for example umlauts, or accented spanish or french vowels.

This can resolve as soon as the new plan is finalized +3 weeks.
