` element but as a raw `#text` node — this cause the title to concatenate with the next paragraph.
This must be corrected by importer.
- Formatting applied across 2 lines in Notion → formatting applied to first line but terminated before linebreak; then reapplied after the linebreak, in Obsidian
- Duplicate text formatting should be removed by Importer.
The above rules should also apply when nested in callouts or quotes, unless stated otherwise.

A text block, equal to a single paragraph but with a
forced linebreak and **text-formatting here**.
A new text block with two consecutive forced linebreaks below—

An indented text bock, equal to a single new paragraph.
A further-indented text block, equal to a single new paragraph.

# Quotes, Callouts + Nesting
It may be useful to encode Obsidian callouts as modified quote-blocks. We just need to check that the `[ ]` are not escaped after import.

# Lists + Nesting
- A level 1 list-item
- Level 2 list-item
- Level 3 list-item
- Level 3 list-item, again
- Level 2 list-item, again
$$f(x)=e^z$$
$$f(x)=e^x$$
- A level 1 list-item, again
# Hashtags
Hashtags have no special meaning in Notion; in Obsidian they create tags when followed by a series of characters that can contain:
- Alphanumeric characters: `[A-Za-z0-9]`
- Hyphens and underscores: `[-_]`
- Unicode `U0080` and above (Non-ASCII): `[^\x00-\x7F]`
- Backslashes for tag nesting: `/`
Note: there must be at least **one** non-numeric character in the tag.
---
The following are recognised as tags in Obsidian so **must be escaped** during import:
- \#123abc
- \#abc123
- \#-
- \#_
- \#/
- \#_123
- \#-123
- \#/123
- \#abc-123
- \#abc_123
- \#abc/123
- \#123/abc
- \#abc/def
- \#θανος
- \#§±_-123
The following are not recognised as tags, so **must not be escaped**:
- #123
- #+abc
- #=abc
- #.abc
- #\abc
- `#abc`
- Display code block:
```Plain
\#abc
```
The following are already escaped for special syntax _eg_ for math or links to headers, so **must not be escaped twice** or the blocks will break:
- $x=a\#b$
- Display math block:
$$x = \begin{cases}
a\#b &: x<0 \\
0 &: x\ge0
\end{cases}$$

# Mathematical Equations
## Math in Callouts
Below is a callout showing a mathematical function.
> [!important] Title for Callout
>
> This paragraph block is about the complex exponential function:
>
> $$f(t)=Ae^{i\omega t},$$
>
> where $t$ is time.
> [!important] Title for Multiline Math Nested in Callout
>
> This paragraph block is about the complex exponential function:
>
> $$\begin{align}
> f(t) &=Ae^{i\omega t} \\
> g(t) &= Be^{i\sigma t},
> \end{align}$$
>
> where $t$ is time. And $f(x) = g(x)$ when $\small A= B = \begin{cases} 1:x>0 \\ 0:x<0 \end{cases}$.
## Math in Text
The complex exponential function is
$$f(t)=Ae^{i\omega t},$$
where $t$ is time.
## Math with Cases
Here is the definition for the absolute value function:
$$|x| = \begin{cases}
-x : & x \lt 0 \\
x : & x\ge 0
\end{cases}$$
## Math with Trailing Spaces & Linebreaks
- Leading/trailing spaces are not an issue in Notion, but they must be removed when converting to Obsidian.
- Linebreaks can be an issue within inline math, especially when nested.
- Double linebreaks can be an issue within display math, especially when nested.
---
1. $f(x)$ has no trailing spaces: `$f(x)$`.
2. $g(x)$ has two trailing spaces: `$ g(x) $`.
3. $h(x)$ has an escaped trailing space: `$h(x)\ $`.
4. $p(x) = e^{x}$ has trailing linebreaks: `$
p(x) = e^{x}
$`.
Multiline display math with trailing space:
```LaTeX
$$ \ \\\mathrm{abs}(x)=|x|
=\begin{cases}
-x : & x \lt 0 \\
x : & x\ge 0
\end{cases}\\
\
$$
```
$$\mathrm{abs}(x)=|x|
=\begin{cases}
-x : & x \lt 0 \\
x : & x\ge 0
\end{cases}$$
## Math With # Variables
Here is a complicated looking bit of math that uses a `#` variable in a user-defined command:
$$\renewcommand{\vec}[1]{\boldsymbol{#1}}
\begin{align*}
\vec{\dot v}_\alpha &=
\vec f_\alpha (t) + \vec\xi_\alpha(t)
\\
\vec f_\alpha (t) &=
{1\over\tau_\alpha} (\vec{ \bar v}_\alpha -
\vec v_\alpha) +
\sum_{\beta≠\alpha}\vec f_{\alpha\beta}(t) +
\sum_{i}\vec f_{\alpha i}(t)
\end{align*}$$
# Internal Links
Currently, Notion does not export standalone internal links to headings or blocks, only standalone links to other pages, or links within table of contents. This appears to be a bug.
