Tips for golfing in 05AB1E

Do you have any tips for code-golfing in 05AB1E, a golfing language created by Adnan?

Your tips should be at least somewhat specific to 05AB1E.

Please post one tip per answer.

#05AB1E ASCII-Art Golfing

The below code helps turn ASCII-art into 05AB1E using a custom base conversion.

This is accomplished by:

1. Listing out the unique characters in the ASCII drawing.
2. Order them by how many times they occur in the string in descending order (most occurring to least occurring characters).
3. Reverse the first two items if the ASCII drawing starts with the most occurring character (to prevent leading 0s in the compressed integer).
4. Map the characters of the input to `0-9A-Za-z` in that order, each distinct character getting its own mapping-character, until every one has been replaced.
5. Base compress it, using the highest base you needed to replace (based on the amount of unique characters).
6. Base convert it again to base-255 (for 05AB1E compression).
7. Format everything in the format: `•<compressed_integer>•“<sorted_distinct_characters>“ÅвJ`.

The `“` allows you to also compress string-quotes `"`; the `Åв` will use this string to base-convert the generated integer using the string as custom base; and `J` will join all these characters together to a single string, which is output implicitly.

Accepts patterns with up to and including 62 unique characters, good for ASCII-art. 
The less amount of unique characters, the better the compression.

**Example output for https://codegolf.stackexchange.com/questions/105853/draw-the-xnor-digital-timing-diagram (214 bytes, 9 unique characters):**

 ┌─┐ ┌─┐ ┌─────┐ ┌─┐ ┌─┐ ┌───┐ 
 A ──┘ └─┘ └─┘ └─┘ └─┘ └─┘ └──
 ┌───┐ ┌───┐ ┌─┐ ┌─────┐ ┌─┐ ┌─┐

 ┌─────┐ ┌─┐ ┌─┐ ┌───┐

Would be:

**(106/214)*100 = 49.53% the size of the original ASCII-art string.**

Which is the same byte-count as [my actual submission for that challenge](https://codegolf.stackexchange.com/a/106621/52210) in 05AB1E (legacy).

#Code explanation:

NOTE: Code is absolutely not golfed. It's quickly written to convert ASCII art to the most efficient compression, so it's quite ugly and long..

If this is an answer to a challenge…

…Be sure to follow the challenge specification. However, please refrain from exploiting obvious loopholes. Answers abusing any of the standard loopholes are considered invalid. If you think a specification is unclear or underspecified, comment on the question instead.
…Try to optimize your score. For instance, answers to code-golf challenges should attempt to be as short as possible. You can always include a readable version of the code in addition to the competitive one. Explanations of your answer make it more interesting to read and are very much encouraged.
…Include a short header which indicates the language(s) of your code and its score, as defined by the challenge.

More generally…

…Please make sure to answer the question and provide sufficient detail.
…Avoid asking for help, clarification or responding to other answers (use comments instead).

\$\begingroup\$ By the way, since 05AB1E has changed the code page, the maximum base is changed from 214 to 255. \$\endgroup\$

\$\begingroup\$ Perhaps something to add to your answer (or modify the generator with), but if less than 10 distinct characters are being used in the ASCII art, you can golf it by two bytes. I.e. your generator gives this 22-byter, but it can be this 20-byter instead. \$\endgroup\$

\$\begingroup\$ @KevinCruijssen the idea was what I was trying to convey, not really claiming that generator is anything good :P. I honestly doubt it even still runs on osabie. I wrote that a looong time ago! \$\endgroup\$

\$\begingroup\$ @MagicOctopusUrn Not sure if it runs in the Elixir rewrite, but it certainly still works in the legacy version. I have already edited the Base-214 to Base-255 about halve a year ago as was mention in Adnan's comment above. Apart from that it works great and I've used it a few times (although golfed it every time further. ;) ). The generation of both the string and number work great! \$\endgroup\$

\$\begingroup\$ Here is an improved version. (Very ugly and fastly written, but it works). It would make your example 108 bytes instead of 113. The improvements I did are: sort the distinct characters on highest occurrence first (unless the highest occurrence is the first character, in which case it'll swap the top two characters) so the compressed integer is as small as possible; using <str><compr_int><int>вèJ instead of your <compr_int><int>BžLR<str>‡; and using " instead of " as string-quotes, so " can be part of the input. \$\endgroup\$

How to Format

create code fences with backticks ` or tildes ~
```
like so
```
add language identifier to highlight code
```python
def function(foo):
print(foo)
```
put returns between paragraphs
for linebreak add 2 spaces at end
_italic_ or **bold**
indent code by 4 spaces
backtick escapes `like _so_`
quote by placing > at start of line
to make links (use https whenever possible)
