Coloured text no longer works in Minecraft bedrock

In the latest release of Minecraft Bedrock Edition, when "§" is typed in a sign, it does not appear and prevents any text from being entered.

Steps:

1: Place a sign in a creative world

2: Open sign UI and type § in the sign

3: Type any kind of text but it does not appear in the sign.

Please fix this bug as soon as possible. I have been depending on colour text to write.

Regards,

Don.
