The surrogate pair (0xD835, 0x2E) is invalid

[yarchiT2022]

Hello!

I'm trying to save presentation with text added as HTML, using AddFromHtml method.

But I get The surrogate pair is invalid, when trying to save Spanish text.
Could you help me solve this issue ?

Here is the full stack trace:

Code: Select all

System.ArgumentException: The surrogate pair (0xD835, 0x2E) is invalid. A high surrogate character (0xD800 - 0xDBFF) must always be paired with a low surrogate character (0xDC00 - 0xDFFF).
